because the base cancels the acid out and the acid cancels the base out to make a more neutral solution
When acids and alkalis are mixed, the pH of the solution changes. Indicators such as litmus paper will change color based on the new pH. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue.
They neutralize each other to form salt and water.
Acids have a pH from 7 to 0 and bases have a pH for 7-14. Water is neutral with a pH of 7. If an equal strength acid and base are mixed together they cancel each out out.
A pH meter or pH indicator paper is commonly used to determine the pH of acids and bases. pH meters provide a numerical measurement of pH, while pH indicator paper changes color based on the pH level to give a visual indication.
Acids and bases are described in the pH scale based on their strength. For instance,lactic acid has pH 6,but curd,obtained from milk itself has pH 3! HCl is called as the "king of acids" with pH 1. {on the pH scale,if any substance has pH 7, its considered acidic, while anything above 7 is basic.} Acids or Bases can be considered as acidic or basic by the colour changes in the pH scale{eg:red to orange[neutral]to violet}.

The fire brigade typically uses pH paper or litmus paper to determine the acidity or basicity of a substance, including acids. pH paper changes color based on the pH of the substance applied to it, helping responders to quickly identify if an acid is present.
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
TURE
Bromothymol blue, also known as bromothymol sulfone phthalein, is a pH indicator for weak acids and bases. It changes color when the pH changes.
This process is called as neutralization of an acid and a base.
The chapstick that changes color based on pH levels is called "mood-changing lip balm."
