The molar concentration of HCL in a solution used to removeboiler scale from plumbing can be determined by titration with aNaOH solution.
10 ml. of the HCL solution is placed in a 125 ml. beaker; 50 ml.of DI water are added along with 1 – 2 drops of phenolphthaleinsolution. It took 44.0 l. of 0.125M NaOH solution to reach an endpoint.
Write the reaction for the equation, calculate the number ofmoles of NaOH required for the titration, the number of moles ofHCL in the HCL sample that was titrated and calculate the molarityin the boiler scale removal solution.
