1- write a) the molecule equation and b)the net ionic equation for the reaction of H2SO4 with NaOH
2- Exactly 25.00 mL of 0.1522M H2SO4 were needed to titrate 45.25mL of NaOH according to the balanced in problem 1 above a)
calculate the moles of NaOH needed for the reaction . b) calculate the molarity of the NaOHsolution
3-one group of students made an error by using HCLinstead of H2SO4 to titrate an unknown solution of NaOH. Would this error change the calculated molarity of the NaOH solution?
