Why is the aqueous solution of a salt of a weak acid and strong base is alkaline?

Why is the aqueous solution of a salt of a weak acid and strong base is alkaline? Correct Answer anionic hydrolysis

The aqueous solution of a salt of a weak acid and strong base is alkaline, due to the anionic hydrolysis and aqueous solution of a salt of a strong acid and weak base is acidic, due to cationic hydrolysis with dilution degree of hydrolysis increases.

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y.

A sample of polystyrene is warmed under reflux in concentrated nitric acid and the clear mixture is poured in water to yield a X coloured precipitate. This precipitate is then extracted with ether and then with NaOH solution followed by washing with water in each extraction. The nitro compounds from the combined final aqueous extract and alkaline extract using concentrated HCl and zinc. The final solution after being diazotized and then cooled is poured into excess of alkaline naphthol to give Y coloured solution. What are the colours X and Y?
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
In making decisions about important questions, it is desirable to be able to distinguish between strong and weak arguments. Strong arguments are those, which are both important and directly related to the question. Weak arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The question below is followed by two arguments numbered I and II. You have to decide which of the arguments a Strong argument is and which a weak argument is. Statement: Is privatizing all the schools in India the best solution to attain 100% literacy rate? Arguments: I. Yes, private institutes are responsible and dedicated towards their work. II. No, education will become unaffordable for poor people.
It is desired to concentrate a 20% salt solution (20 kg of salt in 100 kg of solution) to a 30% salt solution in an evaporator. Consider a feed of 300 kg/min at 30°C. The boiling point of the solution is 110°C, the latent heat of vaporisation is 2100 kJ/kg and the specific heat of the solution is 4 kJ/(kgK). The rate at which the heat has to be supplied in (kJ/min) to the evaporator is
In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The question below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is. Statement: Is capital punishment for heinous crime against women justified?  Argument: I: Yes, this harsh punishment will decrease the crimes against women in the society. II: No, the fear of death is not the solution for such heinous crimes.
