Product description
49. During the conductometric titration of 50 ml of NaBr solution with AgNO3 solution with a concentration of 0.2 mol / l, the following results were obtained:
VT, ml 0 0.6 1.4 2.0 2.8 3.0 3.2 3.4 3.8
ᴂ*103, S/m 139 138 136 135 134 148 160 178 189
where VT is the volume of silver nitrate (0.2 mol/l) used for conductometric titration; ᴂ is the electrical conductivity of the solution.
Construct a conductogram, find an equivalent point; calculate the concentration of sodium bromide solution. Explain the conductogram.
Answer: Vktt \u003d 2.75 ml; C \u003d 0.011 mol / l.
