Question:

Calculate the mass of {eq}MgCO_3 {/eq} precipitated by mixing 10.0 mL of a 0.200 M {eq}Na_2CO_3 {/eq} solution with 5.00 mL of a 0.0400 M {eq}Mg(NO_3)_2 {/eq} solution.

Precipitation Reactions:

Precipitation reactions are reactions that result in the formation of a salt that does not ionize in the solutions after the reaction between two soluble compounds. In precipitation reactions, the mass of the precipitate formed is determined by the moles of the limiting reactant.

We are given that:

  • {eq}[Na_2CO_3] = 0.200 \:M {/eq}
  • The volume of {eq}Na_2CO_3 {/eq} = 10.0 mL = 0.01 L
  • {eq}[Mg(NO_3)_2] = 0.04 \:M {/eq}
  • The...
