What acid is universal indicator goes red?

Answer 1

Hi, just looked this up, here's something to show you how universal indicators work:

Universal indicator and the pH scale

Universal indicator is a mixture of several different indicators. Unlike litmus, universal indicator can show us exactly how strongly acidic or alkaline a solution is. This is measured using the pH scale. The pH scale runs from pH 0 to pH 14.

Universal indicator has many different colour changes, from red for strong acids to dark purple for strong bases. In the middle, neutral pH 7 is indicated by green.Universal indicator shows how acidic or alkaline a solution is

These are the important points about the pH scale:

• neutral solutions are pH 7 exactly
• acidic solutions have pH values less than 7
• alkaline solutions have pH values more than 7
• the closer to pH 0 you go, the more strongly acidic a solution is
• the closer to pH 14 you go, the more strongly alkaline a solution is

Answer 2

When universal indicator turns red, it indicates the presence of a strong acid. This color change occurs at low pH levels, typically below 3.
