(a)
Expert Solution
Interpretation Introduction
Interpretation:
For a given solution, [H3O+][OH-], pH and whether the solution is acidic or basic that has to be determined.
Concept Introduction:
pH:
pH is a scale used to specify how acidic or basic a solution is. It ranges from 0-14. pH 7.0 is considered as neutral solution, pH more than 7.00 is taken as basic solution whereas pH less than 7.0 is considered as acidic solution (at 25oC). It is the measurement of activity of free H+ and OH- in solution.
In this solution [OH-] is greater than [H3O+] and pH more than 7.00.
Hence this is a basic solution having pH=7.21 and [OH-]=1.4×10-5M.

Interpretation Introduction
Interpretation:
For a given solution having given pH, the value of [H3O+], [OH-] and whether the solution is acid or basic that has to be determined.

It is the measurement of activity of free H+ and OH- in solution.
In this solution [H3O+] is greater than [OH-] and pH less than 7.00 and hence the solution is acidic.
Hence this is an acidic solution with [OH-]=2.0×10-9M and [H3O+]=5.00×10−6M.

Expert Solution
Interpretation Introduction
Interpretation:
For a given solution having [OH-], the value of [H3O+] and pH of the solution has to be calculated along with the prediction that whether the solution is acidic or basic.
Concept Introduction:
pH:
pH is a scale used to specify how acidic or basic a solution is. It ranges from 0-14. pH 7.0 is considered as neutral solution, pH more than 7.00 is taken as basic solution whereas pH less than 7.0 is considered as acidic solution (at 25oC). It is the measurement of activity of free H+ and OH- in solution.
As in this solution [H3O+] is greater than [OH-] and pH less than 7.00 and hence the solution is acidic.
Hence this is an acidic solution having pH=4.85 and [H3O+]=1.4×10-5M.
