Test the following salt substances with red litmus and blue litmus papers. Record your observations in the table.

Collect some salt substances with the help of your teacher. Make their salt solutions. Test the salt solutions with blue litmus and red litmus papers. Classify these salts and record your observations in the table.

Which of the following substances are blue

Which of the above substances changed red litmus to blue ?

Which litmus paper do you use to test acids?

Take solutions of some juices of fruits, vegetables, cold drinks and various solutions in beakers test tubes and test them with blue and red litmus papers. List out results in the table, by marking (?) in the relevant column if the colour changes, put (?) if the colour is unchanged.

Collect the salt samples like sodium chloride, aluminium chloride, copper sulphate, sodium acetate, ammonium chloride, sodium hydrogen carbonate and sodium carbonate. Dissolve them in distilled water. Check the action of these solutions with litmus papers. Find the pH using pH paper. Classify them into acidic, basic or neutral salts. Identify the acid and base used to form the above salts. Record your observations in table
