what volume of this solution should be added to 45 ml of 0.867 M sulfuric acid solution to completely neutralize the acid.? The second problem is : 10.0g of Ca(OH)2 was added to enough water to make 435 ml Of solution. However, using M1V1 = M1V2 does not work in this case. What i did was just convert Ba(OH)2 to the mols and use mole ratio to find vols of HNO3 and converted it to liters. In this case, i used the stoic method to solve for the volume which got my the correct answer of : 33.9 ml. The first problem is : What volume of 2.50 M HNO3 is needed to completely neutralize 34.6 ml of 1.22 M Ba(OH)2. So, i have two different problems, and I'm not sure why the technique for solving them is different! They look the same! My main problem is whether i should us M1V1 = M2V2 to solve for volume or to use stoic by using a balanced chemical equation.
