A salt is dissovled in water and the pH of this salt solution is measured with a universal indicator papre. If the pH of solution is less than 7, the salt is most likely to e:

(a). What would you expect the pH of pure water to be? (b). What colour would the universal indicator show in an aqueous solution of sugar? Why? (c). A sample of rain water turned universal indicator paper yellow. What would you expect its pH to be? Is it a strong or a weak acid?

Consider the following statements: (a) Both acids and bases change colour of all indicators. (b) If an indicator gives a colour change with an acid, it does not give a change with a base. (c) If an indicator changes colour with a base, it does not change colour with an acid. (d) Change of colour in an acid and a base depends on the type of the indicator. Which of these statements are correct?
