Question

I need help with Chemistry

Answer 1

Determine the molar concentration of each ion present in the solutions that result from each of the following mixtures:
(Disregard the concentration of H+ and OH- from water and assume that volumes are additive.)

61.9 mL of 0.25 M HCl and 66.0 mL of 1.90 M HCl

a) _____ M H+

b) _____ M Cl-

Answer 2

This is what I am thinking to be true but I am not certain with this.
So HCl disassociates into H+ and Cl-
HCl--> H+ +Cl-
If I have 1M of HCl and it dissociates it makes 1M of H+ and 1M of Cl-
So therefore if I have 0.25moles of HCl and it dissociates I should have 0.25M of H+ and 0.25M of Cl-
The time it would differ if the stoichiometric coefficients are different from one another.

Answer 3

I am so confused.
