What are pH strips?

Here at TestKitCentral.com, we often get many questions asking what pH strips can be used for and how to use them. Therefore  in this blog we ill answer these common questions.

pH strips are used to measure the acidity and alkalinity of different liquids. The pH range goes from 0 to 14. On the pH scale,  less than 7 is acidic, 7 is neutral, and above 7 is alkaline.  The pH strips change color  depending if the liquid is acidic or alkaline. Common liquids pH strips are used on are:
-    Drinking Water
-    Pool Water
-    Urine
-    Saliva

The way you test the pH of drinking water and pool water is by:

1. Remove the strip from the box.
2. Immerse the reaction zone of the strip into the solution for approximately 3-5 seconds or until there is no further color change.**
3. Remove the strip from the solution, wiping the strip along the edge of the vessel to remove excess liquid from the strip.
4. Compare the reaction zones to the color chart on the box holding the strip to the top of the box with the reaction zones to the bottom of the box.
5. Record the results of the closest matching color to the strip.

TestKitCentral.com is not a healthcare facility and therefore we are unable to instruct people  how to test urine and saliva, however Google is a good resources to seek out these instructions. 

Lastly, pH strips come in different ranges. You can get pH strips that cover the entire 0 to 14 pH scale or  there are narrow range pH strips that will  help pinpoint the pH you're trying to measure.

Hopefully you now have a better understanding of what pH strips are!
