Question

The ph value of a solution prepared by dissolving 4 gram of naoh in 100 litre of water is?a. 13b.14c.12d.11

Answer 1

Answer:

The pH scale, which ranges from 0 to 14, tells you how acidic or alkaline a solution is. A pH lower than 7 is acidic, while a pH higher than 7 is alkaline. In mathematical terms, pH is the negative logarithm of the molar concentration of hydrogen ions in the solution. A pH testing strip will tell you that NaOH (sodium hydroxide) is a strong alkaline, but to calculate its exact pH, you have to work out its molarity first.
