Question

calculate the ph of the resulting solution if 17.0 ml of 0.170 m hcl(aq) is added to 22.0 ml of 0.170 m naoh(aq).

Answer 1

The pH of the finsl solution is equal to 2.93

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

C₁ = 0.170 m

V₁ = 17 ml = 0.017 L

C₂ = 0.170 M

V₂ = 22 ml = 0.022 L

C₁V₁ =C₂V₂

0.170× 0.017 L = 2.89 × 10⁻³  ------------- HCl

0.170× 0.022 L = 3.74 × 10⁻³  ------------ NaOH

⇒ 3.74 × 10⁻³  -  2.89 × 10⁻³ = 0.85 × 10⁻³

⇒ 3 + log 0.85

⇒ 3 + -0.07

⇒ pH = 2.93

The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.
