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) an acid and (ii) a base in two separate beakers. She forgot to label the solutions and litmus paper is not available in the laboratory. Since both the solutions are colourless how will she distinguish between the two ?

Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and - How is M related to K ? I. P's rank is three below than that of S.P. is 7th from the bottom in the class. II. There are 17 students between A and S and 5 students between S and B in the class.

An analust is trying to separate a mixture containing the following four organic compounds She dissolved the mixture in ether and treated the solution with aqueous NaOH solution and finally separated the two fractions: Fraction-I (ether) and Fraction-II (aqueous). Later she acidified Fraction-1 and was able to distill the organic compound(s) into ether to obtain third fraction, Fraction-III. Fraction-III was then treated with aqueous NaHCO_(3) and the two layers, ether layer (Fraction-IV) and aqueous layer (Fraction-V) were separated. Also Fraction-I was treated with aqueous HCl solution and the two layers, other (Fraction-VI) and aquores layer (Fraction-VII) were seperated. Answer the following three questions based on the above information. Fraction-V on acidification followed by distillation will give
