what is a an endothermic reaction
An endothermic reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the reaction takes in energy, therefore there is a temperature decrease in the surroundings. Electrolysis is an example of an endothermic reaction but you can create one easily in the kitchen just by dissolving salt or sugar in water.
