You can do a pH test using a pH litmus paper test strip, red cabbage pH indicator (The juice should turn pink in acidic solutions, and green in basic solutions), or similar. Also, any pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid. Xo, Smartiiz.
What else can I help you with?
Are solutions always colourless?
This is commonly used when describing liquids. "Clear" in this context means that you can see through the liquid, so if you put a penny (for example) in a cup of this liquid, you could still see the penny. "Colourless" would mean that the liquid was the same colour as water. Clear but not always colourless means that the liquid may have a tint (so it may be blueish or greenish or some other colour) but you can still see through it.
How would you prove that a given colorless liquid is an acid?
To determine if a colorless liquid is an acid, you can test its pH using pH strips or a pH meter. If the pH is less than 7, it indicates acidity. Additionally, you can conduct a chemical reaction with a known base; if the liquid reacts with the base to form salt and water, it confirms that the liquid is an acid.
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
How much would 25 ml of liquid weigh if it has a density of 1.1?
To calculate the weight of the liquid, you can use the formula: Weight = Volume x Density. Given that the volume is 25 ml and the density is 1.1 g/ml, the weight of the liquid would be 25 ml x 1.1 g/ml = 27.5 grams.
What change would increase the amount of gas able to be dissolved in a given amount of liquid water?
Reducing the temperature and increasing the pressure would increase the solubility of gas in liquid water. This change would allow more gas molecules to dissolve in the water by creating conditions that favor gas dissolution.
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.

What equipment would you need to prove that energy is given out when an acid reacts with a carbonate?
ignited matchstick
What would happen if the weight of an object was less than its buoyant force?
The object would float in a given liquid.
What is the change of state called where energy is given off?
When a substance loses energy, it becomes more compact. A gas would turn to liquid and a liquid would turn to solid.
Why is it a good job that air is odourless and colourless?
Several reasons, the first being that if air had an odour, other smells, including those that alert us to danger, would be harder to detect. Also, our sense of taste would be impaired as a valuable part of that taste is smell. this could prove dangerous if we were to eat something that we otherwise would not due to taste, and it proved toxic. As for it being colourless, if air had a colour, it would be much like fog in impairing vision. Imagine for a second that the air in front of your face was red. The air pressure would determine the depth of colour, however the distance that you could see through would always be less than it would be if colourless.
What characteristic properties would you use to identify a liquid?
Which characteristics are generally given to the atoms that make up a liquid?
What does static head mean?
"Head" is a term given to the weight and resulting pressure of a column of liquid above a given point in the system. Static head means that the head pressure is measured with no liquid actually flowing. Dynamic head would be the pressure of the liquid while it is actually flowing.
What is the metric unit for liquid volume of a sink?
What is the metric unit for liquid volume of a sink
What is the metric unit liquid volume of a sink?
The volume of a sink would be given in litres.
What happen to liquid when it absorbs or released heat?
Liquid would get changed into gas form at this fixed temperature, called as Boiling point of the liquid. The heat thus given will be known as Latent Heat.
