Consider two reactants (A and B) that when mixed form a precipitate C, which can be filtered, dried, and then weighed. Carlos attempts to find the stoichiometric ratios in which A and B mix, by mixing different volumes of the same concentration of solutions of A and B (0.50 M). He records the following data:
Run Vol A (mL) Vol B (mL) Mass C (g)
1 10.0 10.0 1.17
2 20.0 10.0 2.33
3 30.0 10.0 3.50
4 40.0 10.0 3.50
Assuming that the products of the reaction are C and D, and that the stoichiometric coefficients for C and D are 1 and 2 respectively, the balanced chemical reaction will be
( ) A + ( ) B â 1 C + 2 D
