11. Calculate the pH and pOH of a solution that is 0.075 M HCN and 0.06 M NaCN.
Strontium hydroxide is used in refining beet sugar and separating cyrstallizable sugar from molasses. It is commonly found as the octahydrate, Sr(OH)2.8H2O. If a solution is prepared by dissolving 0.45 grams of this compound in sufficient water to make 100 ml of solution, determine the [H+], the [OH-], the pH and the pOH of the solution. Ethylamine (C2H5NH2) is a flammable liquid with an ammonia-like odor that is miscible with water. It is irritating to skin, mucous membranes and to...
