Concept explainers
Interpretation: The order of the given solutions ranging from lowest to the highest pH is to be determined.
Concept introduction: If the salt contains an anion and a cation, both does not react with water, then the pH of the solution is equal to 7.
If the salt contains a cation that does not react with water and an anion that reacts with water and produce hydroxide ion and, then the pH of the solution is greater than 7.
If the salt contains a cation that reacts with water and form hydronium ion and an anion that does not react with water and, then the pH of the solution is less than 7.
If the salt contains an anion and a cation that both are able to react with water, and then the pH of the solution depends on the strength of both cation and anion.
