Place 40 cm 3 of the polyvinyl alcohol solution in the plastic cup. If supplied, add one drop of food colour or fluorescein dye to the solution. Stir well. Measure out 10 cm 3 of borax solution into the beaker and add this to the polyvinyl alcohol solution, stirring vigorously until gelling is complete. This gel is sometimes known as 'slime'.

20/03/2014Sodium borate is easily soluble in hot water. Filter this solution while hot to remove solid impurities and add cautiously/slowly a slight excess hydrochloric acid in that solution, cool it below 0C. It would precipitate much of the boric acid, since it has much lower solubility in cold water (about 2.5g per 100mL water - 0C).

A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also used mixed with water as a flux when soldering gold, silver, etc., in jewelry. It allows the molten solder to flow evenly over the joint in question.
