Question

how to measure accurate ph

Answer 1

We can measure the accurate pH of a solution by using either:

1) pH paper

Or

2) Universal Indicator

Depending of the pH of the solution these will give different colour.

Answer 2

Answer:

pH measurements have been, and continue to be, widely used as a rapid, accurate measure of the acidity of fluids of all sorts. There are two methods for measuring pH: colorimetric methods using indicator solutions or papers, and the more accurate electrochemical methods using electrodes and a millivoltmeter (pH meter).
