Write a balanced equation for the neutralization of aqueous strontium hydroxide with aqueous hydrochloric acid.
A chemist finds a strontium hydroxide solution in lab, but the concentration of this solution is not labeled. A 25.00 mL sample of strontium hydroxide solution is placed in a flask. It takes the addition of 30.00 mL of 0.2695 M HCl to reach the equivalence point. What is the molarity of the strontium hydroxide solution?
[0.1617 M]
What is the molarity of aqueous H+ ions in the 0.2695 M HCl solution used in this titration? (Note-Ââ Aqueous H+ ions are also known as H3O+ ions)
[0.2695 M]
You will learn more about pH later in the semester. It is a measure of the acidity or basicity of a substance. If pH = -Ââlog [H+] or -Ââlog[H3O+], what is the pH of the
aqueous HCl solution?
[pH = 0.5694]
