The student performs a second titration using the 0.10M NaOH(aq) solution again as the titrant, but this time with a 20.mL sample of 0.20MHCl(aq) instead of 0.10MHCl(aq).

1. The box below to the left represents ions in a certain volume of 0.10M HCl(aq). In the box below to the right, draw a representation of ions in the same volume of 0.20MHCl(aq). (Do not include any water molecules in your drawing.).

2. graph in part (d), carefully draw a curve that shows the results of the second titration, in which the student titrates a 20.mL sample of 0.20MHCl(aq) with 0.10MNaOH(aq).
