4. Ammonia and calcium chlorate react to yield nitrogen gas, water, and aqueous calcium chloride. Solution V1,given volume of potassium hydroxide=0.015L M1,Concentration of potassium hydroxide =? V2,volume of HCl given=0.010L M2,Concentration of HCl given=0.92M as we know M1V1=M2V2 M1=M2V2/V1 =0.92*0.010/0,015 =0.613M.
