The explanation for the mixture of anion and cation exchangers being used to deionize water is to be stated. Concept introduction: Ion-exchange resin is a resin or polymer which acts as medium for ion exchange. It is an insoluble matrix which is in the form of micro beads. It is porous usually which provide a large surface area on and inside them. Polystyrene sulfonate is the important component from which most commercial ion-exchange resin is made. These ion exchangers are used for water softening, water purification. Specialized ion exchange resins are also called as chelating resins. To determine: The explanation for the mixture of anion and cation exchangers is used to deionize water.

Heating an alcohol in the presence of sulfuric or phosphoric acid will cause a dehydration to occur: the removal of the elements of water from a molecule, forming an alkene. The reaction usually follows an E1 mechanism. The SN1 pathway is suppressed by using a strong acid whose conjugate base is a poor nucleophile. Further, heating the reaction mixture causes a greater increase in the rate of E1 compared to the rate of Sy1. 3rd attempt h Draw curved arrow(s) to show how the alcohol reacts with phosphoric acid.
