Question

A solution tested in the laboratory shows pH 14. Which of the following statements best describes this solution?

1) It is a highly acidic solution with a high hydrogen ion concentration.
2) It is a highly basic solution with a low hydrogen ion concentration.
3) It is a highly basic solution with a high hydrogen ion concentration.

Answer 1

Answer 2

pH= - log ([H+])

In other words, the higher the pH the lower de hydrogen ion concentration

Also, a solution that is low in hydrogen ions and thus has a pH above 7 is called a basic solution and a solution that is high in hydrogen ions and thus has a pH lower than 7 is an acid.

So in this case, the solution is basic and has a low hydrogen ion concentration

Answer 3

acidic solutions have pH of less than 7, lower the pH, more the acidic solution. alkaline/basic solution have pH value more than 7, higher the pH, more alkaline the solution. An alkaline is a base that is very soluble in water.I'd go for B, because no testing has been done for other alkaline properties.

Answer 4

Number 2 is the right answer
