lora16 [44]

Answer: Option (A) is the correct answer.

Explanation:

A weak acid is defined as a substance which dissociates partially into a solvent. This also means that most of the molecules of a weak acid solution remain insoluble in nature.

A solution in which solute particles completely dissociate into ions in a solvent is known as a strong electrolyte.

Whereas a solution in which solute particles partially dissociate into ions is known as a weak electrolyte.

A molecular compound is a covalent compound and as like dissolves like. So, molecular compounds are not soluble in polar solvent like water.

Therefore, we can conclude that the true statement is weak acid solution consists of mostly insoluble acid molecules.

Answer:

D. 34.5g

Explanation:

Using the following formula to calculate the mass of 1.5moles of sodium (Na);
