My teacher assigned this homework without giving us notes to go from. Please explain these problems for me.
1. What mass of NaCl is needed to precipitate the silver ions from 20 mL of 0.100 M AgNO3?
2. What mass of NaOH is needed to precipitate the Cd2+ ions from 25.0 mL of 0.500 M Cd(NO3)2 solution?
3. a) What volume of 0.115 M HCIO4 solution is needed to neutralize 50.00 mL of0.0875 M NaOH?
b) What volume of 0.128 M HCl is needed to neutralize 2.87 g of Mg(OH)2?
c) If 25.8 mL of AgNO3 is needed to precipitate all the Cl- ions in a 785 mg sample of KCl(forming AgCl), what is the molarity of the AgNO3 solution?
d) If 45.3 mL of 0.108 M HCl solution is needed to neutralize a solution of KOH, how many grams of KOH must be present in the solution?
