How to Lower the PH of Water
The pH scale is in the range from 0 to 14 and determines how basic or acidic a solution is. The neutral media has pH 7. Values below 7 correspond to acidic solutions, while a pH greater than 7 is basic, also referred as alkaline. Distilled water is neutral. However, the water used domestically often has a higher pH--typically in the range from 7.5 to 8.5--due to the presence of dissolved carbonate salts such as sodium carbonate (Na2CO3). In order to use water in a fish tank, plant watering or similar needs you may need to reduce its pH. Does this Spark an idea?
Instructions
-
-
1
Fill in the plastic pipette with the hydrochloric acid solution.
-
2
Add one to three drops of the hydrochloric acid solution to a container with the water being treated.
-
-
3
Cut a 1-inch piece of the pH paper.
-
4
Put the end of the pH paper strip into the water sample for one to two seconds, and then take it out.
-
5
Compare the color of the paper with the scale printed on the pack of pH paper to determine the pH of the water.
-
6
Repeat Steps 2 to 5 until the pH of the water reaches the desired value, for example 6.0.

Tips & Warnings
The amount of the hydrochloric acid that needs to be added for the pH adjustment will depend on the water volume and the concentration of the dissolved carbonate salts.
