Problem 78E

Write a molecular equation for the precipitation reaction that occurs (if any) when each pair of aqueous solutions is mixed. If no reaction occurs, write “NO REACTION.”

a. sodium chloride and lead(II) acetate

b. potassium sulfate and strontium iodide

c. cesium chloride and calcium sulfide

d. chromium(III) nitrate and sodium phosphate

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to determine the molarity of a solution of glycerol made by dissolving 50 mL of glycerol in enough water to make 250 mL of solution. Step1: Molarity is defined as the number of moles of the solute(Here glycerol is the solute) in 1 litre of the solution. Mathematically, Number of moles of solute Molarity(M) = -------------------------------------- ------(1) Volume of solution in litres Step2: In order to calculate molarity of glycerol solution, we have to first calculate the number of moles of glycerol dissolved in the solution. Number of moles can be calculated by the following mathematical formula: Mass of the solute Number of moles(n) =...
