Respuesta :
Strong electrolytes consist of the strong acids and bases and all salts. Weak electrolytes are weak acids and bases and some molecular compounds. The other molecular compounds are non-electrolytes.
1. Citric acid is a weak organic acid. Thus, it is a weak electrolyte.
2. Magnesium lactate is an ionic salt, thus, it is a strong electrolyte.
3. Calcium lactate is an ionic salt, thus, it is a strong electrolyte.
4. Potassium Phosphate is an ionic salt, thus, it is a strong electrolyte.

Further Explanation:
Electrolytes are substances that are able to conduct electricity due to presence of free charged particles or ions in their solutions.
Strong electrolytes are the substances that are completely ionized in solutions. Due to their abilities to release free ions in solutions, these act as good conductors of electricity. Strong acids and bases dissociate completely in solutions so these are good conductors of electricity. Aqueous solution of sodium chloride is an example of strong electrolyte.
Weak electrolytes are the substances that ionize only partially in solutions. Weak acids and bases dissociate partially in solutions so these have conductivity less than that of strong electrolytes but more than that of nonelectrolytes. Aqueous solution of acetic acid acts as weak electrolyte.
Nonelectrolytes are substances that cannot form ions in aqueous solutions. Due to absence of free ions in their solutions, these cannot conduct electricity and act as poor conductors of electricity. Sugar or glucose solution acts as nonelectrolyte.
Citric acid is partially ionized in solutions so it acts as weak electrolyte.
Magnesium lactate is a salt made up of magnesium and lactate ions. Its dissociation occurs as follows:
[tex]{\text{Mg}}{\left( {{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{5}}}{{\text{O}}_{\text{3}}}} \right)_{\text{2}}} \rightleftharpoons {\text{M}}{{\text{g}}^{2 + }} + 2{\left( {{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{5}}}{{\text{O}}_{\text{3}}}} \right)^ - }[/tex]
Since magnesium lactate is ionic salt and dissociates completely in solutions, it acts as strongelectrolyte.
Calcium lactate is a salt made up of calcium and lactate ions. Its dissociation occurs as follows:
[tex]{\text{Ca}}{\left( {{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{5}}}{{\text{O}}_{\text{3}}}} \right)_{\text{2}}} \rightleftharpoons {\text{C}}{{\text{a}}^{2 + }} + 2{\left( {{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{5}}}{{\text{O}}_{\text{3}}}} \right)^ - }[/tex]
Since calcium lactate is ionic salt and dissociates completely in solutions, it acts as strongelectrolyte.
Potassium phosphate is a salt made up of potassium and phosphate ions. Its dissociation occurs as follows:
[tex]{{\text{K}}_{\text{3}}}{\text{P}}{{\text{O}}_{\text{4}}} \rightleftharpoons 3{{\text{K}}^ + } + {\text{PO}}_4^{3 - }[/tex]
Since potassium phosphate is ionic salt and dissociates completely in solutions, it acts as strongelectrolyte.
