# On adding a $20mL$ of $0.1N$ solution to a $10mL$ solution of $0.1N$, the resulting solution will give which of the following result:a. Turns blue litmus redb. Turn phenolphthalein solution pinkc. Turn methyl orange redd. Will have no effect on red or blue litmus paper
As the volume of sodium hydroxide $NaOH$ added to the solution of hydrochloric acid $HCl$ is two times more than the volume of acid where both are of same concentration, here hydrochloric acid is the limiting reagent. The resulting solution will have more portions or more moles of base $NaOH$ than acid $HCl$ and hence it will be basic in nature. A basic solution turns the red litmus solution blue. The indicator phenolphthalein turns to pink colour when added to an alkaline solution. Methyl orange indicator gives a yellow colour with alkaline.
