Can someone please help with these Q's
1)Equal volumes of 4 different acids are titrated with 0.10 M NaOH solution @ 25 * C for complete reaction.
HCN pH: 5.0 Conc L 0.17 M
Ethanoic Acid pH: 3.0 Conc: 0.058 M
Sulphuric acid pH: 2.0 Conc: 0.010 M
Nitric acid ph: 1.0 Conc: 0.10 M
The acid requiring the greatest volume of 0.10 M NaOH for complete reaction is ?
The answer is HCN, can someone please explain how ?
2)
A Standard 0.0500 M Sodium Carbonate solution was prepared ans used to analyse an unknown nitric acid solution. The Volume of Sodium Carbonate solution used was 25.00mL.
1 titration - Volume of Nitric acid used was 22.65 mL
2- titration - 22.40 mL
3- titration- 22.35
4- 22.40
5- 22.38
Write a balanced equation for the reaction
Calculate the conc of the nitric acid solution
And also, when calculating the average titre, do u disregard the first titration?
Thanks
