Which of the following aqueous species will contain mostly reactants?
A
CsOH
B
HNO3
C
Sr(OH)2
D
HClO3
E
Mg(OH)2
Verified step by step guidance1
Identify the nature of each compound: CsOH, Sr(OH)2, and Mg(OH)2 are bases, while HNO3 and HClO3 are acids.
Determine the strength of each acid and base: Strong acids and bases dissociate completely in water, while weak acids and bases do not.
Recognize that HNO3 and HClO3 are strong acids, meaning they will dissociate completely into ions in solution.
CsOH and Sr(OH)2 are strong bases, which also dissociate completely in water.
Mg(OH)2 is a weak base, meaning it does not dissociate completely in water, resulting in a solution that contains mostly reactants (undissociated Mg(OH)2).
