How to test water PH at home (4 methods)

Measuring your water PH levels help you know how your water is acidic or alkaline.

How to test water PH at home

Knowing your water PH level help you know contaminants in your water and what precautions measures you will take

The PH tests are reported on a scale of 0-14 with 7.0 considered neutral, below 7 considered acidic and above 7 considered as neutral.

The water PH is tested using the following kits

  • PH test meter
  • PH test strip
  • Indicator drops

How to test water PH with PH test meter

Learn step by step how to measure the PH of water using PH meter

  • Make sure the test meter is clean
  • Put water you want to test in a container
  • Let the water sit for a moment for the temperature to stabilize.
  • After some time use thermometer to take the water in the container temperature
  • Adjust the test meter to match the sample temperature.
  • Put the tester meter probe in the water and wait for the results.

2: How to test water PH with strips

How to test water PH with strips

Testing water PH with strips is done using PH paper and not litmus paper.

Both PH and litmus measure water acid and base but PH paper will tell you the exact value while litmus paper will indicate whether water is acid or base.

The water PH paper comes with a chart that will help match the color of your strip. The chart has numbers ranging from 0 to 14.

Litmus paper comes in red and blue color. Red litmus paper turns blue if the water is alkaline and blue litmus paper turns red if the water is acidic. In case the litmus paper color did not change then your water is neutral.

Procedure 

  1. Collect your sample water and put in a clean container
  2. Dip the test strip in water
  3. Just in a minute, the color on the paper will change.
  4. IF you are using PH paper it has indicator bars that will change after dipping in water. Match the color of your PH paper against a color chart to determine the numerical value on the pH scale. 

In case you are using litmus paper come in red and blue color.

So if the red litmus paper changes to blue then your water is alkaline and if blue turns red the water is acidic

Pure water without contaminants has a PH level 7 which is considered neutral. A PH level lower than 7 is considered acidic and above 7 is alkaline.

  • Store PH test strip in a dry place
  • Make sure you check the expiration date before using it.
  • Discard used test strip it cannot be used again

3: How to test water PH with indicator drop
How to test water PH with indicator drop
  • Put the small amount of water you are testing in a container
  • Add a few drops of indicator into the water
  • The watercolor will change
  • Match the water color change against a color chart to approximate the numeric value on the PH scale.
4: How to test water PH without a kit

If you don’t have a PH testing kit you can simply locally available items.

You need item such as

  • Vegetable or fruit
  • Distilled water

Before we start the procedure you can experiment using different fruits and vegetables like apple, red rose petals, red onion, blueberries, purple cabbage and more.

For this explanation, I am using purple cabbage

  • Cut the cabbage into pieces
  • Boil two cups of water
  • Add boiled water into the cabbage
  • Stir using a wooden spoon
  • Leave the mixture for 30 minutes
  • After 30 minutes the distilled water color will change
  • Strain the liquid into a container.
  • The liquid is now the PH indicator solution
  • Put a small amount of water you want to test in a container
  • Add a few drops of the liquid (a mixture of cabbage & distilled water) into the water you are testing
  • Watercolor will change
  • Match the color of your water against the color chart.
  • In this case, we do not have any kit so in case the water will turn red or pink that means your water is acidic, purple the water is neutral and blue-greenish or yellow your water is alkaline.
