Answer:
25 mL
Explanation:
The reaction that takes place is:
- Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
First we<u> calculate how many Ca(OH)₂ moles</u> were spent in the titration:
- 25.0 mL * 0.100 M = 2.5 mmol Ca(OH)₂
Then we <u>convert Ca(OH)₂ moles into HNO₃ moles</u>, using the <em>stoichiometric ratio</em>:
- 2.5 mmol Ca(OH)₂ *
= 5.0 mmol HNO₃
Finally we <u>calculate the volume of required nitric acid solution</u>, using the <em>concentration</em>:
- 5.0 mmol ÷ 0.200 mmol/mL = 25 mL
