Chemical Syntheis :At the end of the reaction you are to add ice. Which of the following are reasons for the adding ice?
1) The melting ice dilutes the concentrated acids.
2) The ice cools the reaction thus slowing it down to the point where it is effectively stopped.
3) The excess reactant will be destroyed by the ice.
4) Ice will help filter the product mixture.
5) The ice absorbs the heat generated by the reaction.
