potassium chloride and water - created from Mind Map

KCL+H20= KOH+HCL

ENDOTHERMIC REACTION

EQUIPMENT NEEDED:- THERMOMETER- MEASURING CUP-CUP-POTASSIUM CHLORIDE-WATER-GLASS ROD

Potassium hydroxide- KOH

potassium chloride KCL

water- H20

hydrochloric acid- HCL

An endothermic reaction is a reaction which involves a chemical reaction accompanied by the absorption of heat.

Potassium Chloride is used as a water softener. it dissolves quicker and easier

You know it has reacted when: “it fizzes about on the surface when potassium chloride is added to water”

Hypothesis for experiment:“If you increase the amount of KCL the temperature will keep on decreasing”

Dependent variable is the temperature

independent variable is the amount of potassium chloride being put into the water

the control of the experiment is the volume of the water which is needed for potassium chloride to react with.

the ISA question:whether or not different amounts of KCL will change the temperatureANSWER: the more KCL you put in the lower the temperature goes.

reaction will look abit like this
