Why indicator blank is used in mohr method?
An indicator blank is used in the Mohr method to account for any color changes that may occur due to impurities in the indicator itself. By measuring the blank, you can subtract this error from the titration result, ensuring accurate determination of the analyte concentration.
Is this true or false a change in temperature is always an indicator of a chemical reaction?
False. A change in temperature can indicate a chemical reaction, but it is not always the case. Temperature changes can also result from physical changes, such as phase transitions (e.g., melting or boiling). Therefore, while temperature change can be a sign of a chemical reaction, it is not a definitive indicator on its own.
Why are the colors of the rainbow the same as the color change in universal indicator?
The colors of the rainbow and the color change in universal indicator both result from the interaction of light with different wavelengths and chemical properties. Rainbows are formed through the refraction, dispersion, and reflection of light in water droplets, creating a spectrum of colors. Similarly, universal indicators change color in response to different pH levels, reflecting the presence of hydrogen ions in a solution. Both phenomena illustrate how light and chemical reactions can produce a range of colors, but they stem from different physical and chemical processes.
Would ozone in front of a source of UV light form a shadow on a suitable indicator screen?
Yes, ozone absorbs UV light, so it would block the UV rays from reaching the indicator screen. As a result, a shadow may be observed on the indicator screen where the ozone is present in front of the UV light source.
What is the color of indicator of calamansi?
The indicator of calamansi typically refers to its juice, which has a bright yellow to greenish-yellow color. This vibrant hue is a result of the fruit's high acidity and citrus content. When ripe, the fruit itself can be green or yellow, but the juice extracted is primarily yellow.
What makes universal indicator paper turn red?
Universal indicator paper turns red when the solution has a low pH, indicating that it is acidic. The red color is a result of the indicator's chemical reaction with hydrogen ions in the solution.
What colour will it be on a universal indicator be on slightly acidic water?
A slightly acidic water sample would likely result in a universal indicator displaying a color in the green range, indicating a slightly acidic pH level around 6 or 6.5.
If universal indicator was added to the water after the reaction with caesium what colour would it be?
The universal indicator in water after the reaction with cesium would likely turn purple. Universal indicator changes color to purple in the presence of strong bases like cesium hydroxide, which would be formed as a result of the reaction with cesium and water.

When you add an acid to a carbonate to a universal indicator it turns milky?
This is false. When you add a carbonate to universal indicator it's does not turn milky. In actual fact it turns either like thick bubbly layers or stay the same depending on the acid type are using in this situation. Because of chemistry scientists have sussed that there is no acid which can make the universal indicator turn milky. So the answer to the question is no and if you have to put this question into into a trye or false table then this question would go under FALSE because it does not turn milky.
Positive hpt in seconds could it be a false positive i used Ept non digitial?
It's always possible to get a false positive with any test, including the tests doctors use; however, a positive result within seconds is a pretty good indicator that the test is accurate. Get ready!
What is the importance of accurate centering in universal testing machine?
as proper centering provides the uniform distribution of the load acting upon that particular sample, it gives u the perfect result

What is the result for acid and alkaline respectively when they're tested with red rose indicator?
If red rose indicator is used, acid will turn the indicator red, while alkaline solutions will turn the indicator green.
How does one program a Philips universal remote?
Before attempting to program the remote, ensure that the desired device is turned on and that the corresponding three digit code for the specific device is at hand. Start by pressing the Code Search button until the red indicator stays on. Press the desired mode button and release (TV, DVD),the red indicator should blink and then stay lit.Enter three digit code. A successful code entry will result in the indicator turning off, and, an unsuccessful attempt will result in the indicator flashing. In the event of multiple unsuccessful attempts, use different code for corresponding brand.
Why is research critical in forensic accounting?
Forensic reports always give you accurate result with ample research, else don't accept it as real.
