a. RbOH __ strong base __________

e. NH4I ____ acidic salt ___________

b. CsF ___ basic salt ___________

f. KCH3COO ____ basic salt___________

c. H2SO4 ___ strong acid __________

g. NH3 ____ weak base ____________

d. HNO2 ____ weak acid ___________

h. SrBr2 ___ neutral salt ____________

6. (6 pts) Circle the ions in the list below that are neutral: Cl- NH4 + Mg2+ NO3 - K+ CN

Answer #1

Ans 5 :

when the species readily gives off its proton it is a strong base otherwise weak. If it gives off hydroxide ions readily than a strong base otherwise weak. The salt formed by strong acid strong base is neutral ; weak acid and strong base is basic and strong acid and weak base is acidic.

So here :

a) RbOH : strong base

e) NH4I : acidic salt

b) CsF : basic salt

f) KCH3COO : basic salt

c) H2SO4 : strong acid

g) NH3 : weak base

d) HNO2 : weak acid

h) SrBr2 : neutral salt
