[tex]\boxed{\boxed{\huge\text{$\rm pH$ of solution $\rm=2.92$}}}[/tex]
Explanation:
pH stands for "potential of Hydrogen." It's a scale used to specify the acidity of a solution. The pH scale ranges from 0 to 14, where:
- A pH of 7 is considered neutral. This is the pH of pure water.
- pH values below 7 indicate acidity, with lower numbers being more acidic. For example, lemon juice has a pH around 2.
- pH values above 7 indicate basicity, with higher numbers being more basic. For instance, baking soda solution can have a pH around 9.
The pH scale is logarithmic, meaning each whole pH value below 7 is 10 times more acidic than the next higher value, and each whole pH value above 7 is 10 times more basic than the next lower value.
The pH of a solution can be calculated using the following formula:
[tex]\boxed{\Large\text{$\rm pH=-log_{\,10}[H^+]$}}[/tex]
[tex]\text{Where $\rm [H^+]$ represents the concentration of $\rm H^+$ ions in the solution.}[/tex]
Knowing this, the only value that matters in the above given question, is the concentration of H⁺ = 1.20×10⁻³ M. Plugging this value into our formula:
[tex]\Large\text{$\rm pH=-log_{\,10}[1.20\times10^{-3}]$}[/tex]
[tex]\boxed{\boxed{\Large\text{$\therefore\rm pH$ of solution $\rm=2.92$}}}[/tex]

The pH of a solution with a hydrogen ion concentration of 1.20 x 10^-3 M can be calculated using the formula pH = -log[H+], which equals approximately 2.92.
To calculate the pH of a solution where the concentration of hydrogen ions [H+] is 1.20 imes 10⁻³ M, you can use the formula:
pH = -log[H+]
Plugging in the given concentration:
pH = -log(1.20 imes 10⁻³)
Using a calculator, you will find the pH to be:
pH = 2.92
This calculation tells us the acidity of the organic acid solution in question.
