Question

a) How many mL of 0.500M silver nitrate solution should be added to 50.00mL of 0.0700M potassium chromate solution, assuming 100% yield?


b) If only 95.0% yield is assumed, how many mL of silver nitrate solution should be added to obtain 1.000g of silver chromate?

Thanks in advance.

Answer 1

2 AgNO3 + K2CrO4 -> Ag2CrO4 + 2 KNO3

V = 2x50x0.07/0.5 = 70 ml

b) 84 ml
