Write the names and formulas of 10 salts.
Salts:
Example of salts:
Write the chemical name and formula of (a) common salt, and (b) caustic soda.
(a) What is a salt ? Give the names and formulae of any two salts. Also, name the acids and bases from which these salts may be obtained.
(b) What is meant by 'a family of salts of salts'? Explain with examples.
(c) What is meant by 'hydrated' and 'anhydrous' salts? Explain with examples.
(d) Write the names, formulae and colours of any two hydrated salts.
(e) What will be the colour of litmus in an aqueous solution of ammonium chloride salt?
Two metals X and Y form the salts XSO4 and Y2SO4, respectively. The solution of salt XSO4 is blue in colour whereas that of Y2SO4 is colourless. When barium chloride solution is added to XSO4 solution, then a white precipitate Z is formed along with a salt which turns the solution green. And when barium chloride solution is added to Y2SO4 solution, then the same white precipitate Z is formed along with colourless common salt solution.
(a) What could the metal X and Y be ?
(b) Write the name and formula of salt XSO4.
(c) Write the name and formula of salt Y2SO4.
(d) What is the name and formla of white precipitate Z ?
(e) Write the name and formula of the salt which turns the solution green in the first case.
