Consider again the solution made by diluting 10.0 mL of the 0.50 M NaCl by adding distilled water until 100 mL of solution are produced.


Has the concentration of the diluted salt solution increased, decreased, or remained constant?

every time you add water to a solution the concentration decreases

Answer:

Decreased

Explanation:

Using the dilution equation:

C₁V₁ = C₂V₂

where C₁ and V₁ are concentration and volume before dilution and C₂ and V₂ concentration and volume after dilution

Plugging the numbers we have,

0.5 M x 10 ml = C₂ x 100 ml

C₂ = (0.5 M x 10 ml) / 100 ml = 0.05 M

Therefore, the concentration of the diluted salt solution has decreased.
