What volume of 0.135 M HCIO4 solution is needed to neutralize 60.00mL of 8.95 times 10-2 M NaOH? What volume of 0.120 M HC1 is needed to neutralize 2.96g of Mg(OH)2 ? If 25.8mL of AgNO3 is needed to precipitate all the Cl- ions in a 0.795-mg sample of KCl (forming AgCl), what is the molarity of the AgNO3 solution? If 45.1 mL of 0.112 M HCl solution is needed to neutralize a solution of KOH, how many grams of KOH must be present in the solution?
