Equilibrium - Ohlone College

(Fe3+ is the iron(III) ion, present here in a solution of Fe(NO 3) 3 acidified with HNO 3. SCN-is the thiocyanate ion, present here in a solution of KSCN. Fe(SCN)2+ is the monothiocyanatoiron(III) ion, one of the so-called complex ions.) This reaction is particularly well suited to investigation because equilibrium is reached very quickly.

Fe(NO3)3 + NaOH = what? | Yahoo Answers

Mar 12, 2009· Best Answer: Fe(NO3)3 + 3NaOH -> Fe(OH)3 (s) + 3NaNO3 The product will be precipitation of Fe(OH)3 (and also NaNO3 which is soluble and unseen) which could be seen as browny-red jelly at the bottom of test tube. A very low concentration of reactants only makes a browny solution/colloid, not precipitated.

Tutorial 3 THE MOLE AND STOICHIOMETRY - EIU

Tutorial 3 THE MOLE AND STOICHIOMETRY A chemical equation shows the reactants (left side) and products (right side) in a chemical reaction. A balanced equation shows, in terms of moles, how much of each substance is involved in the reaction. Stoichiometry is the study of the relationships of quantities of substances in a chemical reaction.
