The combined masses of the acid and base, the enthalpy change would be less than anticipated.
What is pH?
An aqueous solution's pH indicates how basic or acidic it is; a pH of 7 or less indicates that the solution is basic. 7 is regarded as the neutral pH. The pH scale typically ranges from 0 to 14, though extremely strong acids and bases may have pH values that are higher than 14.
As 50 ml of HCl are needed to make 50 ml of NaOH, but Jacob only added 40 ml, all the H+ ions are consumed, and this limiting reactant is what prevents the production of the desired product.
[tex]NaOH + HCl - > NaCl + H2O[/tex]
Instead of NaOH, HCl would act as the limiting reactant. This error would result in fewer product. Due to the volume shift, this would also have an impact on the pH levels of the solution. Additionally, by reducing the combined masses of the acid and base, the enthalpy change would be less than anticipated.
