Question

calculate the concentration of NaoH when NaoH was used 12ml for 6ml of 0.3M oxalic acid​

Answer 1

Answer:

Calculate the concentration of the hydrochloric acid.

Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3

Amount of sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.

From the equation, 0.005 mol of NaOH reacts with 0.005 mol of HCl.

Volume of hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3
