Answer :
Strong electrolyte solutes are, [tex]HNO_3,KOH\text{ and }NaBr[/tex]
Weak electrolyte solute are, [tex]HCOOH,CH_3OH\text{ and }CH_3NH_2[/tex]
Non-electrolyte solutes are, [tex]C_{12}H_{22}O_{11}[/tex]
Explanation :
Strong electrolyte : It is defined as the species that can completely dissociates into ions in its aqueous solution.
Weak electrolyte : It is defined as the species that is partially dissociates into ions in its aqueous solution.
Non-electrolyte : It is defined as the species that does not dissociates into ions in its aqueous solution.
Now we have to determine the solute as a strong electrolyte, a weak electrolyte, or a non-electrolyte.
(1) [tex]HNO_3[/tex]
[tex]HNO_3[/tex] on complete dissociation to give hydrogen ion and nitrate ion. So, it is a strong electrolyte.
(2) [tex]KOH[/tex]
[tex]KOH[/tex] on complete dissociation to give potassium ion and hydroxide ion. So, it is a strong electrolyte.
(3) [tex]HCOOH[/tex]
[tex]HCOOH[/tex] on partial dissociation to give [tex]HCOO^-[/tex] ion and [tex]H^+[/tex] ion. So, it is a weak electrolyte.
(4) [tex]CH_3NH_2[/tex]
[tex]CH_3NH_2[/tex] on partial dissociation to give [tex]CH_3NH^-[/tex] ion and [tex]H^+[/tex] ion. So, it is a weak electrolyte.
(5) [tex]NaBr[/tex]
[tex]NaBr[/tex] on complete dissociation to give sodium ion and bromide ion. So, it is a strong electrolyte.
(6) [tex]CH_3OH[/tex]
[tex]CH_3OH[/tex] on partial dissociation to give [tex]CH_3O^-[/tex] ion and [tex]H^+[/tex] ion. So, it is a weak electrolyte.
(7) [tex]C_{12}H_{22}O_{11}[/tex]
There is no dissociation of [tex]C_{12}H_{22}O_{11}[/tex] into ions. So, It is a non-electrolyte.
