Question

wateris the observation when two drops phenolphthalein is added to the solution obtained with water?justify your answer​

Answer 1

Explanation:

The colour of the final mixture when added HCl to it

The colour of the final mixture when added HCl to itThe colour (pink colour) will disappear.

The colour of the final mixture when added HCl to itThe colour (pink colour) will disappear.the reaction between an acid and a base is known as neutralisation in this reaction and acid neutralizes the effect of acid and a base this reaction result in the formation of salt and water and energy in the form of heat is evolved.

The colour of the final mixture when added HCl to it

The colour (pink colour) will disappear.

the reaction between an acid and a base is known as neutralisation in this reaction and acid neutralizes the effect of acid and a base this reaction result in the formation of salt and water and energy in the form of heat is evolved.

Process:

fill half in test tube HCl and two drops of phenolphthalein to it start it continuously. next add Sodium Hydroxide till pink colour appears now add one drop of HCl the pink colour disappears so it is evident that when a solution is acidic it gives no colour this shows that neutralization reaction has occurred
