Question

What is the action of water on (i) Sodium (ii) Zinc (iii) Copper​ ?
__________________________​

Answer 1

Explanation:

This reaction releases hydrogen, which reacts with oxygen explosively. Zinc salts cause a milky turbidity in water in higher concentrations. Additionally, zinc may add an unwanted flavour to water. Normally less than 10% of your daily copper intake is through water consumption.

Answer 2

Answer:

Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour. The reaction is slower than that of potassium (immediately below sodium in the periodic table), but faster than that of lithium (immediately above sodium in the periodic table). As the reaction continues, the concentration of hydroxide increases.
