Question

A 50.0 mL sample of 12.0 M HCl is diluted to 200 mL. What is true about the diluted solution?

Answer 1

The concentration of the solution reduces and the number of moles of solute isn't affected.

Data;

• V1 = 50mL
• C1 = 12.0M
• V2 = 200mL
• C2 = ?

Facts about the diluted solution

1. When the solution is diluted, the concentration changes and this time, the concentration reduces.

Using dilution formula

$c_1 v_1 = c_2 v_2\\12 * 50 = c_2 * 200\\c_2 = \frac{600}{200} \\c_2 = 3M$

The concentration of the solution reduces.

2. The number of moles remains the same.

When a solution is diluted, the number of moles remains the same because there's no change in the mass of the solute.
