Question

10-37 The following four diagrams represent aqueous solu- tions of four different acids with the general formula HA. Which of the four acids is the strongest acid? IV Ш II 10-38 Using the diagrams shown in Problem 10-37, which of 191s the four acids is the weakest acid? 10-39 Which of the terms weak, strong, monoprotic, diprotic,
#38

Answer 1

All of the acids given below are monoprotic acid with general formula HA. Dissociation of these acids, HA 2 H+ + A The acid that dissociate more is stronger acid. Strongest acid IIII 3 1 No of dissociation: 2 So the acid that is shown in the figure 4 is the strongest acid.

1) NaCN and KCN : Here both are salt 2) HCl and LiCl : Here LiCl is salt but HCl is acid. 3) Na2SO4 and NaOH : Here Na2SO4 is salt but NaOH is base 4) Al(NO3)3 and Ca(NO3)2 : here both are salt
