RICE chart
open-in-new
<p>An ICE table or RICE box or RICE chart is a tabular system of keeping track of changing concentrations in an <a href="/facts/Equilibrium_reaction/y8ToYXHp">equilibrium reaction</a>. ICE stands for <i>initial, change, equilibrium</i>. It is used in chemistry to keep track of the changes in <a href="/facts/Amount_of_substance/tQVyNLCp">amount of substance</a> of the reactants and also organize a set of conditions that one wants to solve with. Some sources refer to a RICE table (or box or chart) where the added R stands for the <i>reaction</i> to which the table refers. Others simply call it a concentration table (for the acid–base equilibrium). </p>
