Question

98g of H2SO4 react with 80g of NaOH. the amount of reactants left will be a. 20g H2SO4 b. 10g of NaOH c. 15g of NaOH d. none at all​

Answer 1

Answer:

none at all

Explanation:

concentration of H2SO4= 98/98= 1M

so concentration of H+ ions will be 2M as each H2SO4 release 2 H+ ions

concentration of NaOH =80/2=2M

so concentration of OH- will be 2M

2M H+ + 2M OH- = 1M Na2So4 + 2M H2O

so noting will be left
