Q2 A solution has a [OH ]=4.0×10 M. What are the [H3O*] and the pH of the solution? Q3 A sample of 0.0084 mol of HCl is dissolved in water to make a 1500-mL solution. Calculate the molarity of the HCl solution, the [H,O*], and the pH. For a strong acid such as HCI, the [H,O*] is the same as the molarity of the HCl solution. HCI(aq)+ H2O(1) →H;O*(aq)+CI (aq)

Q2 A solution has a [OH ]=4.0×10¯³ M. What are the [H30*] and the pH of the
solution?
Q3 A sample of 0.0084 mol of HCl is dissolved in water to make a 1500-mL solution.
Calculate the molarity of the HCI solution, the [H;O*], and the pH. For a strong
acid such as HCI, the [H,O*1 is the same as the molarity of the HCl solution.
HCI(aq)+H,0(1) –H;0*(aq)+Cl¯ (aq)
