Copper(II) sulfate, which is commonly used in agriculture as a soil additive, has a concentration of .24 M.

Question

Copper(II) sulfate, which is commonly used in agriculture as a soil additive, has a concentration of .24 M. If it is mixed with 1.6 L of 1.3 M lithium hydroxide, what is the volume of copper(II) sulfate needed to neutralize the solution?

Answer 1

Copper (II) sulfate and Lithium hydroxide react in 1:2 ratio

Multiplying the molarity and volume of Lithium hydroxide gives you ( 1.6 X 1.3) = 2.08 moles.

Since for every two moles of Lithium hydroxide it is only one mole of Copper (II) sulfate, the moles of Copper(II) sulfate are only1.04 moles.

Molarity = moles /liters

0.24 = 1.04/ Liters

to get the liters divide the moles by its liters

1.04/.24 = 4.3 liters
