Question

part 2: adding acetic acid
first, lets try adding some acetic acid to the solution.
to review, here is the chemical equation again: $ch_3cooh
ightleftharpoons h^++ch_3coo^-$

1. what happened to the ph of the solution?

hint: think about the color of the solution. how does it relate to the ph?
ph increased, meaning the solution is more acidic
ph increased, meaning the solution is more basic
ph decreased, meaning the solution is more acidic
ph decreased, meaning the solution is more basic
ph stayed the same

Explanation:

Step1: Understand acid - pH relationship

Adding an acid like acetic acid ($CH_3COOH$) to a solution increases the hydrogen - ion ($H^+$) concentration.

Step2: Recall pH formula

The pH is defined as $pH = -\log[H^+]$. As $[H^+]$ increases, the value of $-\log[H^+]$ decreases.

Step3: Determine the effect on acidity

A lower pH means the solution is more acidic.

Answer:

pH decreased, meaning the solution is more acidic
