How can metal ions be identified

WebIons of group 1 metals (Li +, Na + and K +) form soluble hydroxides. Therefore, they are identified using flame tests and not by adding sodium hydroxide solution. WebExplain. Suppose you put a hot object in contact with a cold object and observe (with some wonder) that heat flows from the cold object to the hot object, making the cold one colder and the hot one hotter. This process would violate. A. only the first law of thermodynamics. B. only the second law of thermodynamics.
