You are provided with one solid: solid $$\(\mathbf{E}\)$$. Do the following tests on solid $$\(\mathbf{E}\)$$, recording all of your observations at each stage. Tests on solid E Divide solid $$\(\mathbf{E}\)$$ into two approximately equal portions in two boiling tubes. Gently heat the first portion of solid $$\(\mathbf{E}\)$$. Record your observations. ................................................................................................................................................ . ................................................................................................................................................ . .......................................................................................................................................... To the remaining portion of solid E, add about 5 cm depth of distilled water. Place a stopper in the boiling tube and shake to dissolve solid $$\(\mathbf{E}\)$$ and form solution $$\(\mathbf{E}\)$$. Divide solution $$\(\mathbf{E}\)$$ into four approximately equal portions in one boiling tube and three test-tubes.
