Correct Option - 1

Detailed Solution:

During removal of temporary hardness of water.

$\begin{array}{l} M g {(H C O_{3})}_{2} \overset{B o i l}{\to} M g {(O H)}_{2} + 2 C O_{2} ↑ \\ C a {(H C O_{3})}_{2} \overset{B o i l}{\to} C a C O_{3} + H_{2} O + C O_{2} \end{array}$

Aromaticity drives the highest enolic percentage of given structure:

The solubility of AgCl will be maximum in which of the following?

alok kumar singh

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.

When 800mL of 0.5 M nitric acid is heated in a beaker, its volume is reduced to half and 11.5g of nitric acid is evaporated. The molarity of the remaining nitric acid solution is x × 10^-2M. (Nearest Integer)

(Molar mas of nitric acid is 63g mol^-1)

Vishal Baghel

Remaining volume of solution = 400 ml

Mass of HNO3 = 25.2 – 11.5 = 13.7

Molarity = $\frac{(13.7 / 63)}{(400 / 1000)}$ = 0.54 M = 54 × 10^-2 M

Given below are two statements : one is labeled as Assertion A and the other is labeled as Reason R.

Assertion A: Phenolphthalein is pH dependent indicator, remains colourless in acidic solution and gives pink colour in basic medium.

Reason R: Phenolphthalein is a weak acid. It doesn’t dissociate in basic medium.

In the light of the above statements, choose the most appropriate answer from the options given below.

alok kumar singh

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.

$\underset{(C o l o u r l e s s)}{H P h (a q .)} ? H^{+} + \underset{(P i n k)}{P h^{-}}$

For the equilibrium $A ⇌ B$ , the variation of the rate of the forward (a) and reverse (B) reaction with time is given by:

alok kumar singh

At equilibrium rate of forward and backward reaction becomes equal.
