Question

3. Suppose you pour 20 mL of silver nitrate into a beaker with 80 mL of water (H20) in it. You also pour 20 mL of silver nitrate into a separate beaker, but this one contains 80 mL of salt water (NaCl). Is the percent strength of the silver nitrate the same in both of these solutions

Answer 1

No,cause in that beaker with salt water you have extra Cl- ions,which can react
with silver nitrate

AgNO3 + NaCl = AgCl (not soluble compound) +
NaNO3

so in that beaker which is without salt water percent and
concentration of AgNO3 is higher
