Part B

Next the strontium hydroxide solution prepared in part (a) is used to titrate a nitric acid solution of unknown concentration.Write a balanced chemical equation to represent the reaction between strontium hydroxide and nitric acid solutions.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation / Answer

A)

[Sr(HO)2] = mol/L

[Sr(HO)2] =mass/(MW*L)

[Sr(HO)2] =10.4//(121.63*47/1000)

[Sr(HO)2] =1.8192 M

B)

2HNO3(aq) + Sr(OH)2(aq) = 2H2O(l) + Sr(NO3)2(aq)
