I have been given a substance which is unknown in my class. The substance is white in colour and is in a powder form. I have conducted a few tests and have found out that the substance is a covalent compound.
Properties of the substance
- Has a low melting point. When the item was melting it left a yellow/orange colour liquid, later it hardened and retained the same yellow/orange colour.
- Soluble in water
- Does not conduct electricity in solid state
- Does not conduct electricity when dissolved in water
- pH of 3-4
- Soluble in Ethanol
- Is not a sugar, used bennedict's solution and did not turn red instead gave of vapour and started bubbling.
From these steps I have concluded that the substance is a covalent compound. However, I need to find exactly what type of elements is in the covalent compound. If you could suggest a test to conduct to figure out what type of elements there are, it would be very helpful. Thanks.
