According to my equation calcs... one mole of Na2CO3 should react with one mole of H Cl ?
Anyone confirm? So that means that 25 ml of 0.1 M/L Hcl will neutralise 25 ml of 0.1M/L Na2 Co3 in soln?

Re: Titration ratios
Hi Rainbow sky,
The reaction between HCl and Sodium Carbonate is actually a 2 to 1 Ratio:
As follows:
2HCl + Na2CO3 ----> 2NaCl + CO2 + H2O
2 : 1 ----> 2:1:1
The 2 to 1 ratio I have described for you in red..
I hope this has clarified this for you.
Cheers,
Robb.....

Re: Titration ratios
Na2CO3 + 2HCl => 2NaCl + H2O + CO2
so you would need twice as much HCl compared to Na2CO3
