In reversible hydrocolloids, which factor primarily controls the change between sol and gel states?

Show Answers

Amount of filler and plasticizer presentWater content expressed as a percentage by weightLevel of potassium sulfate concentrationTemperature variationspH level of the solution

Explanation

The reversible change from sol to gel and back in hydrocolloids depends mainly on temperature. Other factors like filler concentration, water content, or potassium sulfate do not directly control this phase transition.
