Questions and Problems Q.1 Complete the following table: Q2. The label on the shampoo claims that it is pH balanced. What do you think "pH balanced" means? Q3 A solution has a [OH]=1×10−5M. What are the [H3O+]and the pH of the solution? Q.4 A sample of 0.0020 mole of HCl is dissolved in water to make a 2000 -mL, solution. Calculate the molarity of the HCl solution, the [H2O+], and the pH. For a strong acid such as HCl, the [H3O+]is the same as the molarity of the HCl solution. HCl+H2O⟶H3O∗+Cl−
