Question

What mass of solute will dissolve in 100g of water at the following temperatures?
• KNO3 at 70°C =
• NaCl at 100°C=
• NH₂Cl at 90°C=

Answer 1

$KNO_3$ at 70°C = 130 gram

NaCl at 100°C= 40 gram

NH₂Cl at 90°C= 70 gram

What is solubility?

Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature.

Amount of a substance (called the solute) that dissolves in a unit volume of a liquid substance (called the solvent) to form a saturated solution under specified conditions of temperature and pressure. Solubility is expressed usually as moles of solute per 100 grams of solvent.

Hence,

$KNO_3$ at 70°C = 130 gram

NaCl at 100°C= 40 gram

NH₂Cl at 90°C= 70 gram
