What is the name of the chemical which changes colour when it is mixed with acids or alkalis?
If you want the general term, it's "indicator". If you want a specific one ... methyl red, litmus, or bromothymol blue are some examples (there are lots of others).
What colour does universe indicator with antacid solution?
The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
If soda water or any indicator which will change into the colour of red?
Methyl Orange is red in an acidic solution.
When a drop of universal indicator is added to water what is the colour change?
Pure water is neutral so the color will be green.
What is an 'indicator reaction'?
An indicator reaction is a chemical reaction used to detect the presence of a particular substance or to monitor the progress of a reaction. It involves a change in color, pH, or some other physical property that indicates the presence or absence of the target substance. These reactions are often used in analytical chemistry and testing.
Can an indicator change colour twice?
Yes.
What is the only sure sign of a chemical change?
The only sure sign of a chemical change is the formation of new substances with different chemical properties from the original substances. This can be seen through changes in color, formation of gas, precipitation of a solid, or changes in temperature.

What is the colour change observed as the end point is approached when borax is titrated against a solution of HCl using screened methyl orange indicator?
When titrating borax with HCl using methyl orange indicator, the color changes from yellow to orange as the end point is approached. This color change is due to the change in pH from basic (yellow) to acidic (orange) as the titration progresses.
