A student prepared solution sof (i) an acid and (ii) a base in tow separate beakers. She forgot to label the soltuion s and litmus paper is not avialable in the laboratory. Since both the solutuons are colourless how will she distinguish between the two ?

A student prepared solutions of (i)and acid and (ii) a base in two separate beakers. She forget to label the solutons and litmus paper is not available in the laboratory. Since both the solution are colourless, how will she distinguish between the two?

A student prepared solution of (i) acid and (ii) base in two separate beakers but forgot to table the solution and litmus paper is not available in the lab. Since both solution are colourless how will you distinguish between there using (a) phenolphthalein (b) methyl orange.

Dilute hydrochloric acid and dilute sulphuric acid are both colourless solutions. How will the addition of barium chloride solution to each help to distinguish between the two ?

A student prepared 20% NaOH solution in a beaker containg water. The observation made by him are as follows : (i) NaOH are in the form of pellets. (ii) It dissolves readily in water. (iii) The beaker appears cold from outside. (iv) Red litmus paper turns blue when dipped in the solution. The correct observation are :
