Question

Why is it important to check the conductivity and pH of pure water for comparison

Answer 1

To check that underlying conditions are stable of the water source, checking for the purity of the water (conductivity highlights levels of impurities), and pH determines the alkalinity or acidity of water. 

Answer 2

it is important to check the conductivity and pH of pure water to:

1- to check the purity of water and if it healthy or not , and the water source.

2- we have to measure the PH to know the alkalinity or acidity of water. If the PH > 7 so it is acidic , if PH < 7 so it is alkaline.

3- we have to measure the conductivity of the water as it is an indication for the impurity level. and it shouldn't be high to keep the water healthy.
