Consider the given examples listed here, find out which substance from the list will turn phenolphthalein pink? (a) vinegar ( b)
egoroff_w [7]

Answer:

(d) soap.

Explanation:

A soap is obtained by alkaline hydrolysis of a fat to yield the soap and glycerol. This process is known as saponification.

A soap solution is usually basic. Since phenolphthalein turns pink in an alkaline solution, then when phenolphthalein is added to a soap solution, the solution soon turns pink because it is alkaline in nature.

As a matter of fact, a soap sometimes has almost the pH of baking soda!

2 H2 + 2 NO → N2 + 2 H2O the observed rate expression, under some conditions, is: rate = k[NO]2 Which of the following mechanism
guapka [62]

Explanation:

Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.

               Rate \propto [\text{concentration of reactant}]^{n}

                                  = k [\text{concentration of reactant}]^{n}

where,     k = rate constant

                n = order of reaction

For the given reaction, 2H_{2} + 2NO \rightarrow N_{2} + 2H_{2}O

Hence, its rate will be as follows.

                   Rate = k[H_{2}][NO]

Also, it is known that slowest step in a chemical reaction is the rate determining step.

Hence, for the given rate law correct reaction is as follows.

Step 1 : H_{2} + NO \rightarrow N + H_{2}O (slow)

Balancing this equation it becomes H_{2} + 2NO \rightarrow N_{2}O + H_{2}O (slow)

Step 2: N_{2}O + H_{2} \rightarrow N_{2} + H_{2}O (fast)
