magnesium hydroxide
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
calcium hydroxide
potassium chloride (KCl)
Both must be in solution, aqueous, to fit the definition, which is; an acidic solution has enough hydronium ion concentration to hydroxide concentration to have a pH lower than 7.0, while a basic solution has enough hydroxide ion concentration to be at a pH higher than 7.0. An acid and base are different in definition. Subtle, but a real difference.
basic
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
Ammonium Hydroxide NH4OH
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
calcium hydroxide
potassium chloride (KCl)
This solution is basic.

4.0x 10^ -11
basic
Neither - its a measure of hydrogen ion concentration.
Yes, this solution (NH4OH, ammonium hydroxide) is alkaline.
Because this solution contain sodium hydroxide.
