Question
1. a) Which of the metals ranked in part D is most easily oxidized? moones um (Wal gels oxiditted Pk easiest b) Give the formula for the metal oxide which would be expected to be most casily.resduaced, List 3 possible reasons why you might not observe a reaction even though the activity series indicates it should occur. 2. 3. Explain your litmus test results in part A when the sodium and potassium reacted in water. When Ca metal is placed in an aqueous solution of NaCl, the calcium slowly disappears and bubbles form. A litmus test shows that the solution turns basic. Is this evidence that Ca is more active than Na? Explain briefly! 4.Explanation / Answer
1.a
Magnesium is easily oxidized because of in activity series Mg is most active metal.
b. Cu is easily reduced metal. 2Cu +O2 ------> 2CuO
c. in acivity series top metals are easily oxidizing metals.
in acivity series top to bottom reduction potential values are increases.
In activity series top metals are displacement the bottom metals from ii's salt solution.
d. 2Na + 2H2O ----->2 NaOH + H2 sodium more react with water. This reaction is highely exothermic reaction.
Sodium metal burn on surface of water.The solution is basic nature.In basic solution red litums turn to blue colour.
2K + 2H2O -------> 2KOH + H2 . The solution is basic nature.In basic solution red litums turn to blue colour.
e. Sodium more react metal than calcium.sodium displcement the calcium metal.
Calsium is less reactive metal than sodium.
in acitivity series above metals are displacement the below metals from its salt solution.
