How do you find the pH of a solution?

To determine the pH of a solution, you can use several methods:

1. pH Indicator Strips – These strips change color depending on the acidity or alkalinity of a solution. The colors are compared to a standard chart to determine the pH.
2. Litmus Paper – Litmus paper turns red for acidic solutions and blue for basic (alkaline) solutions.
3. pH Meter – A pH meter is a precise tool that gives a numerical value for the pH of a solution, where values range from 0 (strongly acidic) to 14 (strongly basic), with 7 being neutral.
   This process allows scientists and students to measure the acidity or alkalinity of various solutions accurately.
