Question

if the color of universal indicator changes from green to yellow, predict the change in ph​

Answer 1

Seeing that a pH universal indicator color changes from green to yellow, it`s required to predict the change in pH.

The universal pH  indicator consists of chemical compounds that change color as the  solution pH values change indicating how acid or alkaline the solution is. Green color indicates that a solution is neutral (pH 7) and yellow color indicates weak acid ( pH 3 – 6).
