Question

At 20°C, which substance is the most soluble?potassium nitrate (KNO3)potassium bromide (KBr)sodium chloride (NaCl)sodium chlorate (NaClO3)

Answer 1

At 20 degrees Celcius, NaClO3 (sodium chlorate) is more soluble

Step-by-step explanation

Solubility of a solute in a solvent is defined as the maximum concentration that may be achieved under given conditions when the dissolution process is at equilibrium.

One of the factors that affect solubility is temperature. The solute becomes more soluble as the temperature increases.

At 20 degrees Celcius, NaClO3 (sodium chlorate) is more soluble
