Question

When an acid like HCl dissociates in water, it essentially is ________.Select one:a. making the water more basicb. raising the pH of the solutionc. adding H+ to the water, making it less acidicd. adding H+ to the water, making it more acidic

Answer 1

1) Acidic solution. An acidic solution has a high concentration of H+ ions.

2) Basic solution. A basic solution has a high concentration of OH- ions.

3) HCl chemical reaction.

`HCl+H_2O\rightarrow H_3O^++Cl^-`

You can also write it as follows

`HCl+H_2O\rightarrow H^++Cl^-`

4) pH scale.

When the concentration of H+ is high, the solution is acidic. H+ lowers the pH of the solution.

Option D.
