1. You titrate 125 mL of a solution of ammonia (NH3) with 1.0 M HClO4. The equivalence point is reached after adding 25 mL of the titrant.
a.) What kind of titration was this (WA/SB; WB/SA; SA/SB; polyprotic A (or B) /SB (or SA); WA/WB)?
b.) Write a balanced reaction for the titration.
c.) What is the concentration of the NH3?
d.) Would the resulting solution be acidic, basic, or neutral?
4. Write the Keq expression for the following equilibria:
a.) H3PO4 (aq) + H2O (l) ? H3O + (aq) + H2PO4 - (aq)
b.) HCO3 - (aq) + H+ (aq) ? H2O (l) + H2CO3 (aq)
c.) PbSO4 (s) ? Pb+2 (aq) + SO4 -2 (aq)
