Study the given reaction and identify the process which is carried out.

Identify the cation in each of the following case Sodium hydroxide solution when added to solution C gives bluish white precipitate which is insoluble in excess.

Identify the cation in each of the following case Ammonium hydroxide solution when added to the solution B gives white precipitate which dissolves in excess

In a class of 40 students, the marks obtained (out of 50) are as given below: Draw a histogram to represent the given data.

A white substance (A) reacts with dilute H_(2)SO_(4) to produce a colourless suffocating gas (B) and a colourless solution (C )/ The reaction of gas (B) with potassium iodate and starch solution produce a blue colour solution. Aqueous Solution of (A) gives a white precipitate with BaCl_(2) solution which is soluble in dilute HCl . Addition of aqueous NH_(3) or NaOH to (C ) produced first a precipitate which dissolves in excess of the respective reagent to poduced a clear solution. Similarly addition of excess of potassium ferrocyanide to (C ) produced a precipitate (D) which also dissolves in aqeous NaOH giving a clear solution. Identify (A),(B),(C ) and (D ). Write the equation of the reactions involved.

A student was given a sample of two tissues. He observes the tissues under the microscope and draws their figures (1 and 2) as shown below . Identify the tissues (1 and 2)

When a white crystalline compound X is heated with K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) a reddish brown gas A is evolved. On passing A into caustic soda solution, a yellow coloured solution of B is obtained. Neutralizing the solution B with acetic acid and on subsequent addition of lead acetate, a yellow precipitate C is obtained. When X is heated with NaOH solution, a colourless gas is evolved and on passing this gas into K_2HgI_4 solution, a reddish brown precipitate D is formed. Identify A, B, C, D and X. Write the equations of reactions involved.
