Hi, i have 2 questions about my chemistry homework i can not figure out
The first question is:
1)Silver ions can be precipitated from an aqueous solutions by the addition of aqueous chloride:
Ag+(aq) + Cl-(aq) ---->AgCl(s)
Silver chloride is virtualy insoluble in water so that the reaction appears to go to completion. How many grams of solid NaCl must be added to 25.0mL of 0.326 M AgNo3 solution to completely precititate the silver?
The second question is:
2) A 31.5 mL aliquot of H2SO4(aq) of unknown concentration was titrated with 0.0134 M NaOH(aq). It took 23.9 mL of the base to reach the endpoint of the titration. The concentration (M) of the acid was_____. (be sure to write a balanced chemical equation for the neutralization reaction.)
I already balanced the equation.
H2SO4 + 2NaOH ------> Na2SO4 + 2H2O
Can anybody tell me how to go about solving either of these questions?
