Activity 1.10 - Reacting with acids, alkalis and solutions of salts

• Characterize resistance of plastic to acids, alkalis and solutions of salts

• Test tubes, clap stand , different kinds of plastic, cotton, metal and wood

• Before the experiment, formulate your hypotheses about action of acids, alkalis and solutions of salts on plastic materials and natural substances
• Carry out an experiment in which you will study the resistance of the above-mentioned substances to the action of acids, alkalis and solutions of salts.

Fill the test tubes with different acids, alkalis and solutions of salts. Put a particular kind of plastic, cotton, metal and wood into each test tube. Write your findings into the table
