##### Calcium Hydroxide titration with HCl
« on: March 15, 2004, 05:40:45 PM »
Hello to all. I have titrated a calcium hydroxide (Ca(OH)2) solution against a hydrochloric acid solution. The hydrochloric acid has a concentration of 0.030 mol dm-3. I need to calculate the concentration of the calcium hydroxide solution. Does anyone know how I can do this...
My average titre was 20.38 CM3.
Any help or ideas would be so cool.
Thankyou

The 2 moles of hydrochloric acid will react with each mole of Ca(OH)2. Therefore determine how many moles of HCl was used, and the amount of Ca(OH)2 will be twice that.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Yes, correct.
Do you know how to calculate?

2H+ + Ca(OH)2 => Ca2+ + 2H2O

moles Ca(OH)2 reacted = 2 X moles of H+ reacted

moles of H+ reacted = molarity of HCl x corresponding volume

concentration of Ca(OH)2 = moles of Ca(OH)2 / corresponding volume

I hope you understand the workings..
