Stoichiometry Problems for Reaction in Aqueous Solutions
1.How many grams of Ca(OH)2 are needed to neutralize 25.0 mL of 0.250 M HNO3?
2.How many milligrams of sodium sulfide are needed to completely react with 50.00 mL of a 0.100 M aqueous solution of cadmium nitrate, to form a precipitate of CdS(s)?
3.How many grams of NaOH are needed to neutralize 25.0 mL of 0.50 M H2SO4 solution? (b) How many liters of 0.400 M HCl(aq) are needed to react completely with 0.200 mol of Pb(NO3)2(aq), forming a precipitate of PbCl2(s)?
4. One commercial method used to peel potatoes is to soak them in a NaOH solution for a short time and then remove the potatoes and spray off the peel. The NaOH concentration is normally 3 to 6 M, and the solution must be analyzed periodically. In one such analysis, 55.7 mL of 0.500 M H2SO4 is required to neutralize 25.0 mL of
