The graph above shows the titration of 183 mL of 0.047 M hydrofluoric (HF) with 0.21 M sodium hydroxide solution.

What is the [F−]/[HF] ratio at point A on the curve? (Express as a decimal fraction, i.e. 0.333 instead of 1/3).


What is the [F−] concentration at point A?

 Tries 0/99


What volume of NaOH solution is required to titrate the sample from point A to point B?

 Tries 0/99
