The pair of elements that will form an ionic bond are Strontium and Chlorine.
Oxidation is the Loss of Electrons, and Reduction is the Gain of Electrons
(Remember oil rig - Oxidation Is Loss, Reduction Is Gain)
Since water loses an electron, it gets oxidised, and since carbon dioxide gains an electron, it gets reduced.
Since both oxidation and reduction occurs, it is called a Redox reaction
