Aromaticity drives the highest enolic percentage of given structure:
During removal of temporary hardness of water.
Due to common ion effect solubility of AgCl will decreases in KCl, AgCl and AgNO3 but in deionized water, no common ion effect will takes place so maximum solubility.
Remaining volume of solution = 400 ml
Mass of HNO3 = 25.2 – 11.5 = 13.7
Molarity = = 0.54 M = 54 × 10-2 M
Phenolphtalein is a pH dependant indicator. It is a weak acid which is colourless in acidic medium but gives pink colour in basic medium. The pink colour is due to its conjugate form. Phenolphthalein dissociates in basic medium. Therefore, assertion is true but reason is false.
