Some neutralization examples of the problem with the solution are: 1. To titrate 45 mL of 0.0452 M HNO3, how many mL of 0.0955M Ba (OH)2 solution is required? From the given problem we can assume that M₁ = 0.0452M, M₂ = 0.0955, V₁ = 45mL. The equation or formula to solve this problem is, M₁V₁ = M₂V₂. mygoodeye photographyWebSolvation of HCl and NaOH produced heat aswell. However, since NaOH and HCl exist and solvated ions and not as the molecules in solution we can neglect the enthalpy of solvation during neutralization unless we add solid NaOH to a HCl solution. When in solution the NaCl isnt formed.
