Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and ...

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests ...

Some metal cations have distinctive colours when held in a blue Bunsen burner flame. A nichrome wire is used to hold the test solid – nichrome has no flame colour of its own and it has a high ...

Chemical Engineering is concerned with the design and operation of processes which convert materials and energy into the higher value products we use every day. It understands the processes which ...
