2 Chemistry Grade 11 Questions

In summary, the differences between the dissociation of an acid (or base) in water and the ionization of an acid (or base) in water are that the first involves a reaction with water while the second involves water's role in stabilizing the final ionic charges. To determine the exact concentration in mol/L of calcium hydroxide, the student can conduct an acid-base titration experiment using the given bottles of hydrochloric acid and calcium hydroxide. This experiment involves gradually adding one solution to the other until a neutralization point is reached, allowing for the calculation of the unknown concentration of calcium hydroxide.

Hi,
I need help on these two questions.

1.Describe the differences between the dissociation of an acid (or base) in water and the ionization of an acid (or base) in water.

2. A student working in a chemistry laboratory is given 2 bottles, each filled with 1.00L of clear and colourless liquid. The first bottle is labeled "Hydrochloric Acid - 2mol/L" and the other just simply says "Calcium Hydroxide" Describe an experiment that this student can conduct in order to determine the exact concentration in mol/L of calcium hydroxide.

I ask these questions because I have no idea what to do. Please help.

Thank You.

Well from what i remember off my Freshman Chemistry. The Theory of Acid-Bases by Arrhenius will help to answer your first question.

1.Describe the differences between the dissociation of an acid (or base) in water and the ionization of an acid (or base) in water.

The first pertains to a reaction of the acid/base with water (Ka and Kb), the second refers to water's role in stabilizing the transition states and final ionic charges.

you could just set up an acid-base titration experiment.

My teacher has done an acid-base titration experiment during a class but I don't know how it works. Could someone explain it to me?
Thanks
