In the activity students of class 8 investigated which solution produced biggest temperature change while reacting with dilute acid
They took Sodium hydroxide, Sodium hydrogen carbonate, Potassium hydroxide in three separate conical flask and added dilute HCl.
They measured the initial temperature of the reaction and final temperature of the reaction with the help of thermometer
They founded that
In reaction of sodium hydroxide and potassium hydroxide temperature increases thus they are exothermic reactions
In reaction with sodium hydrogen carbonate with dilute acid the temperature decreases thus they are endothermic reactions
