answer:
i am pretty sure you use cross charges for this.
so i think it is the third choice.
Answer:
pH = 4.17
Explanation:
According to the molar concentration you stated, pH of the solution is: 4.17
Remember that pH = - log [H⁺]
and [H⁺] = 10^-pH
When:
pH > 7 → Basic solution
pH = 7 → Neutral solution
pH < 7 → Acid solution
