Answer : The correct option is, (C) $OH^-$ ions as the only negative ions in solution

Explanation :

According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion $(H^+)$ and a bases is a substance that ionizes in the water to give hydroxide ion $(OH^-)$ .

A sample of $Ca(OH)_2$ is considered to be an Arrhenius base because when it dissolves in the water to yield $OH^-$ ions as the only negative ions in solution.

Hence, the correct option is, (C)

What is the percent by mass of a solution containing 4. 0g of solute in 100g of water? (Percent by mass formula: (mass of solute

Hoochie [10]

B
mass of solute - 4.0 g
mass of solution - 100g + 4.0g = 104g
4/104 = 0.03846
0.03846 • 100 = 3.8%
