Question

due to this pH concept maybe restricted for solutions of less than 1 molar


Explain me the above sentence in simple words ​

Answer 1

Answer:

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

• Acidity (low pH) Issues Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. When pH is low, your household plumbing pipes may leach copper into the water causing green stains on bathroom sinks and porcelain surfaces.
• Salts of weak bases and strong acids do hydrolyze, which gives it a pH less than 7. This is due to the fact that the anion will become a spectator ion and fail to attract the H+, while the cation from the weak base will donate a proton to the water forming a hydronium ion.
