3.5g of CuCl2.2H2O were dissolved and reacted with excess Na2SO3 in the presence of HCl. After filtration, 1.5g of CuCl crystals was obtained. Calculate the %yield.
1. Write and balance the equation.
2. Convert 3.5g CuCl2.H2O to grams of the product. Use stoichiometry. Here is a worked example. Just follow the steps.
3. %yield = (grams product/theoretical yield in grams)*100.
balanced equation of cucl2.2h2o+na2so3
