    Exercise 5.What volume of a 0.234M solution of Ba(OH)2 would be required to
    precisely neutralize 750.0mL of a 0.7532M solution of the weak acid
    CH3COO-H?
    Exercise 6.A 10.00mL sample of stock phosphoric acid solution H3PO4 (aq) is
    diluted to 50.00mL,and then titrated with a known KOH solution.If 55.58mL
    of that 1.554M KOH(aq) solution is required to neutralize all of the acid,what
    was the molarity of the original H3PO4 (aq) solution?

    優(yōu)質(zhì)解答
    Answer 5.1207.06mL
    Process:750.0mL*0.7532M/(0.234M*2)=1207.06mL
    Answer 6.2.88M
    Process:1.554M*55.58mL/(3*10.00mL)=2.88M
