Normality of acids is also related to equivalents, comparing an acid's potential proton donating to a monoprotic strong acid. What is the Normality of 5M H2S?

Question

CRB Normality of acids is also related to equivalents, comparing an acid's potential proton donating to a monoprotic strong acid. What is the Normality of 5M H2S?

(A) 5 N

(B) 2.5 N

(C) 10 N

(D) 15 N

Answer 1

The normality will be equal to or greater than the molarity. It varies as a function of the number of hydrogen atoms. For H₂S, we have TWO hydrogen atoms, so 5 M H₂S is equal to 10 N H₂S because there are two equivalents in H₂S.
