How many grams of potassium chlorate are needed to saturate 100g of water at 70 celsius? Group of answer choices 48 g 100 g 34 g

marissa [1.9K]

Answer:

34g of potassium chlorate.

Explanation:

A saturated solution is a solution that, under a temperature, has the maximum amount of solute possible. The maximum amount that a solvent can dissolve of a solute is called <em>solubility.</em>

The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.

That means, to saturate 100g of water at 70°C you need yo add:

<h3>34g of potassium chlorate.</h3>
