Ionic compounds will produce ions
Answer:
Scientists can ensure their results are reliable by making multiple observations and repeating trials during experimentation. They should also use proper units to communicate with other scientists, and make sure the experiment is repeatable.
Explanation:
I believe C is the balanced equation.
The pH of a solution that contains 0.0011 moles of KOH in 393 mL of solution is 2.56. Details about pH can be found below.
<h3>How to calculate pH?</h3>
The pH of a solution can be calculated using the following expression:
pH = - log [H3O+]
However, the hydrogen concentration of the KOH solution can be calculated as follows:
concentration = 0.0011 mol ÷ 0.393 L
concentration = 2.798 × 10-³M
The pH of KOH = - log [2.798 × 10-³M]
pH = 2.56
Therefore, the pH of a solution that contains 0.0011 moles of KOH in 393 mL of solution is 2.56.
