Yes, the blue substance in some pool thermometers is typically non-toxic alcohol or mineral spirits, not Mercury. If a pool thermometer breaks and spills the blue liquid, it should be safe as long as it is properly cleaned up and disposed of to prevent environmental contamination.

What is the liquid in the themometer?
The liquid in a thermometer is typically mercury or alcohol. Mercury is commonly used in traditional thermometers, while newer digital thermometers may use alcohol. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature accurately.
Is mercury red in thermometers?
The planet Mercury is grey, similar in colour and general appearance to our moon. Red Mercury is a chemical made of Iodine and Mercury. It was used as a medicine a long time ago before people realised it was actually poisonous. It is either in the form Mercury(I) iodide or Mercury(II) iodide.
Difference between clinical and a laboratory thermometer?
A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature. A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature.
What gas produces blue light bulb?
Blue light bulbs typically use a gas called mercury vapor to produce light. When an electric current passes through the mercury vapor, it creates ultraviolet light which then interacts with a phosphor coating on the inside of the bulb to produce visible blue light.
Which clock is more accurate There are two clocks of different colors the red clock is broken and doesn't run at all but the blue clock loses one second every 24 hours?
When a clock breaks or stops, the hands of the clock "freeze" at that time. But time itself goes on, and twice in a 24 hour cycle the hands will show the correct time. But a clock that loses time, however slowly will always be always be incorrect.
What is in the laboratory thermometer?
There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).
What is blue liquid in thermometer?
A thermometer in which the liquid is blue or red probably contains alcohol with a coloring agent added to make it easier to see. If the liquid is silvery and metallic-looking, it's most likely mercury or one of the new less toxic alloys such as Galinstan (gallium, indium, and tin).
What are mercury thermometers used for?
If the bulb is red, blue, purple, green or any other color, it is not a mercury thermometer. Mercury thermometerscan be used to determine body temperature (fever thermometers), liquid temperature, and vapor temperature.
What is in the glass thermometer?
Red or blue - alcohol. Silver - mercury. There are some other possibilities as well (Galinstan, for instance), but those are by far the most likely.
What is the liquid in the themometer?
The liquid in a thermometer is typically mercury or alcohol. Mercury is commonly used in traditional thermometers, while newer digital thermometers may use alcohol. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature accurately.
How do you know if its mercury or alcohol your thermometer broke in and around the pool Help?
Mercury is a metal so it will sink to the bottom of the pool where an alcohol will float. Actually, it's more likely that alcohol will simply disperse into the pool; low molecular weight alcohols are extremely soluble. A simpler way to tell is the color: mercury is silver and looks, well, metallic; alcohol in thermometers is generally colored either red or blue simply to make it easier to see. (A lot of people think mercury is red, but it isn't. Some mercury COMPOUNDS such as cinnabar are red, but those are not used in thermometers.) The fact that the liquid in the thermometer is metallic does not necessarily mean that it is mercury; it might be a gallium alloy. However, since mercury is toxic, if you're not sure it's probably safer to assume that it was mercury and treat the spill accordingly.
What substances are in a thermometer?
Red and blue coloured alcohols are the most common in modern times, although mercury was used for a long time before people figured out how toxic it was.
What color thermometer is used for axillary temperature?
A blue-tipped thermometer is commonly used for axillary temperature readings.
What is best known to be used in thermometers?
It depends on the thermometer. An old-style liquid thermometer might contain: * mercury (silvery) * alcohol (usually dyed red or blue for visibility) * an alloy of sodium and potassium (silvery) * an alloy of gallium, indium, and tin (silvery) * any of a number of other things depending on the temperature range to be measured Electronic thermometers contain a thermocouple plus electronics to turn the potential generated by the thermocouple into a temperature reading.
What do they use instead of mercury thermometer?
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
How should you dispose of an old thermometer?
It depends on the thermometer. If the thermometer is made of glass and filled with a silver liquid, that liquid is mercury. Your local environmental protection organization might be able to tell you where you could safely dispose of it. Otherwise, you might check with companies that deal with scrapping out old cars, which contain mercury switches, or fluorescent bulbs, which contain mercury. If the thermometer does not have a silver liquid in it, it doesn't contain much or any mercury, and it should be possible to toss it with your normal household trash. When a glass thermometer has a red or blue liquid, the liquid is alcohol or, rarely, some other organic liquid such as kerosene. It's not that much of a threat. Metal coil thermometers with dial pointers are just scrap metal when you need to dispose of them. Electronic thermometers have batteries, which might have some mercury but might not. If in doubt, take the battery out and put it in a battery recycling bin. If you must throw it out in the trash, at least the amount of mercury in it (if any) will be small. The circuits themselves contain the same contaminants and heavy metals that any piece of electronics would, but since the amount of circuitry in an electronic thermometer is small, the amount of waste in one is small also.
Why do people use alcohol in thermometers instead of water?
Firstly, mercury has a freezing point of about -38Co. So a mercury thermometer cannot be used below this. Alcohols have a much lower freezing point, some around -100Co . Thus they are useful at much lower temperatures. Though alcohols are usually colourless, they can easily be dyed, usually red or blue. Alcohols however have lower boiling points, and this limits the maximum temperature at which they may be used.
