You are supplied with five solutions: A, B, C, D and E with Ph values

1.	You are supplied with five solutions: A, B, C, D and E with Ph values as follows:A= 1.8, B = 7, C= 8.5, D = 13, and E=5Classify these solutions as neutral, slightly or strongly acidic and slightly or strongly alkaline.Which solution would be most likely to liberate hydrogen with:(a) magnesium powder,(b) powdered zinc metal. Give a word equation for each reaction.
Answer» A = Strongly acidic B = neutral C = Weakly alkaline D = Strongly alkaline E = Weakly acidic (a) Solution A (acidic solution) + Mg H₂ + Mg salt (b) Solution A (acidic solution) + Zn H₂ + Zn salt

Answer»

A = Strongly acidic

B = neutral

C = Weakly alkaline

D = Strongly alkaline

E = Weakly acidic

(a) Solution A (acidic solution) + Mg H₂ + Mg salt

(b) Solution A (acidic solution) + Zn H₂ + Zn salt
