Question

A student completed two experiements in which several samples from two hydrochloric acid solutions, solution #1 and solution #2, were titrated with the same solution of sodium hydroxide until each sample of acid was completely neutralized.

Use the particulate-level representations of the two HCl solutions to describe the data the student would have recorded in his laboratory notebook during the titration experiments (i.e., what did he observe? What measurements did he make? Did the data differ between the two experiments?).

Explanation / Answer

in solution -1

6 HCl molecules are neutralised by adding 6 NaOH molecules.

whereas in solution -2

3 HCl molecules are neutralised by ading 3 NaOH MOLECULES

SOLUTION-1 IS MORE CONCNTRATED THAN SOLUTION-2

Because in solution -1 less no.of water molecules as compared to solution -2.Therfore solution -1 is less diluted than solution-2

the volume of NaOH is more consumedin in solution-1 as compared to the solution-2 .because it is more concentrated than solution-2.
