You use Universal Indicator solution.
You test for pH so you know whether a liquid is an acid or base. Depending on the answer, the liquid has a different response to what you mix in with it. In the body, pH balance is important as well.
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
Add chalk (Calcium carbonate) if it is an acid the chalk will 'fizz' as it reacts and it will give off carbon dioxide gas. Or just use a universal indicator solution or test with litmus paper.
You can use a pH paper.
Use a pH-paper.
The pH test paper is used to detrmine the pH; immerse a piece of paper in the solution and compare with the color scale.
use to test the acid level in liquid.
PH scale
the pH of a neutral liquid, which is water, is neither acidic or basic, therefore it pH value is between 7and8 or 7.5 in the ph scale
Some ways to determine the pH of a liquid include using pH test strips, pH meters, or pH indicator solutions. pH test strips change color based on the acidity or alkalinity of the liquid, pH meters provide a numerical pH value, and pH indicator solutions change color to indicate the pH level.

Place a piece of Ph paper in the liquid and remove. The color the paper turns will tell you the acid level.
You can measure the pH of an unknown liquid using a pH meter or pH test strips. Simply dip the pH meter or test strip into the liquid and observe the reading or color change, respectively. This will give you an indication of the pH level of the unknown liquid.
The pH of a liquid can be measured in a number of different ways, using liquid, paper or electronic testers. The most common ways to test aquarium water is with either liquid or paper test kits. pH test kits are available online at www.bigalsonline.com
You test for pH so you know whether a liquid is an acid or base. Depending on the answer, the liquid has a different response to what you mix in with it. In the body, pH balance is important as well.
To test the pH of soil at home, you can use a pH testing kit specifically designed for soil. Collect a soil sample, mix it with water, and then dip the pH testing probe into the mixture. The pH level will be indicated on the testing kit's scale.
most bottles will not have the pH of the liquid inside, so you will need a pH test strip to know the pH of the liquid inside the bottle.
