If you want to test the alkalinity (base) or acidity of a liquid, just use the pH strip to help determine the level. If you've never used a pH strip, it looks like a plain strip of paper and the colorful chart looks like the stuff you'd see in art class. Luckily, once you understand how color coding works, reading pH strips is easy!
Step
Part 1 of 2: Using the pH Strip
Step 1. Make sure the test strip can test the range you need
The pH scale covers a range of 14 digits, with 7 being neutral pH. A number less than 7 means it is more acidic, while a number greater than 7 means it is more alkaline. Some strips only test part of the spectrum. So, make sure the strips you buy can cover the pH range you want to test.
Step 2. Read the instructions on the box to find out how long the pH strip should be left on
Some test strips only need to be immersed in the liquid to be examined for a second, while others take up to 20 seconds for the results to be read. Understand the instructions to make sure the readings are accurate.
Step 3. Dip one end of the test strip into the material you want to examine
You don't need to dip the entire strip into it. Hold one end of the strip and dip the other end into the liquid, then lift it off after the allotted time.
You can use a test strip to check the pH level of any liquid
Step 4. Compare the stripe colors with the provided chart
pH strips are sold as a package with the pH color chart. After the test strip has finished reacting, compare it to the chart and adjust the color of the strip to the color on the chart. Once you find a number that matches the color on the test strip, that's the pH result.
Acids are represented by warm colors, such as red and orange, while bases are associated with cooler colors, such as blue and green
Step 5. Search the internet for general charts if you don't have them
If the color chart is missing or the test strip doesn't come with a chart, just search the internet for generic charts. Even if the colors are not exactly the same, you can get an estimate of the pH level.
Part 2 of 2: Knowing What to Test
Step 1. Test tap water to make sure it's acid-neutral
Water is neutral, meaning it must have a pH balance of 7. Most drinking water has a pH range of 6.5-8. 5. Test your drinking water to see if its pH is in that range. Otherwise, there may be contaminants in your water supply.
Step 2. Keep the pool water in balance by testing the pH level
The swimming pool should have a pH balance between 7.4 and 7.6. Add a product made of soda ash if the pH of the pool water is below 7.4 or muriatic acid if the pH is more than 7.6.
Step 3. Test the pH level of the aquarium water, if applicable
The pH balance in the aquarium is an important factor for maintaining fish health. Since natural water pH levels can vary, it makes sense that different fish have different pH requirements. Make sure you know the best pH range for your fish and check the water to make sure it is within that range.
There are many products available at pet supply stores to raise or lower the pH level of aquarium water
Step 4. Measure the pH of saliva to determine oral health
The average pH of saliva is 6.7, but the normal range is between 6.2-7. 6. If you check your saliva and the numbers are significantly different, you are at higher risk of cavities or gingivitis.
