Question

(a) What is the volume of 0.220 M HClO4 solution is needed to neutralize 78.0 mL of 0.0675 M NaOH? (b) What volume of 0.25 M HCl is needed to neutralize 7.89 g of Mg(OH)2 ? (c) If 87.8 mL of AgNO3 is needed to precipitate all the chloride ions in a 429-mg sample of KCl (forming AgCl), what is the molarity of the AgNO3 solution? (d) If 55.5 mL of 0.41 M HCl solution is needed to neutralize a solution of KOH, how many grams of KOH must be present in the solution?
