4. test your understanding of titrations. a) write a balanced equation for the neutralization of aqueous strontium hydroxide with aqueous hydrochloric acid. b) 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. i. define equivalence point. ii. what is the molarity of the strontium hydroxide solution? [0.1617 m] iii. what is the molarity of aqueous h+ ions in the 0.2695 m hcl solution used in this titration? (note- aqueous h+ ions are also known as h3o+ ions) [0.2695 m] iv. you will learn more about ph later in the semester. it is a measure of the acidity or basicity of a substance. if ph = -log [h+] or -log[h3o+], what is the ph of the aqueous hcl solution? include correct significant figures! [ph = 0.5694]
