- Define the following:- pH- Buffer- pKaarrow_forwardA water solution contains 60% Na2S202 together with 1% soluble impurity. Upon cooling to 10°C, Na2S202 • 5 H2O crystallizes out. The solubility of this hydrate is 1.4lb Na2S202 • 5 H20/lb free water. The crystals removed carry asadhering solution 0.06 lb solution/lb crystals. When dried to remove the remaining water (but not the water of hydration), the final dry Na2S202 5 H20 crystals must not contain more than 0.1% impurity. To meet this specification, the original solution, before cooling, is further diluted with water.
