Asolution is made by adding 50.0 ml of 0.200 m acetic acid (ka = 1.8 x 10–5) to 50.0 ml of 1.00 x 10–3m hcl. (a) calculate the ph of the solution.

Final pH of the solution: 2.79.

Explanation:

What's in the solution after mixing?

,

where

.

Acetic (ethanoic) acid:

.

.

Hydrochloric acid HCl:

.

.

HCl is a strong acid. It will completely dissociate in water to produce H⁺. The H⁺ concentration in the solution before acetic acid dissociates shall also be .

The Ka value of acetic acid is considerably small. Acetic acid is a weak acid and will dissociate only partially when dissolved. Construct a RICE table to predict the portion of acetic acid that will dissociate. Let the change in acetic acid concentration be . .

.

.

Rewrite as a quadratic equation and solve for :

.

The pH of a solution depends on its H⁺ concentration.

At equilibrium

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
