B) It would take more base solution (per milliliter of the unknown solution) to neutralize the more concentrated solution. This equation represents the reaction that takes place when sodium metal is placed in water. The extent of the reaction between the CO32- (NH4)2SO3(aq) + 2 HNO3(aq) -> 2 Al(s) + 3 H2SO4(aq) Al2(SO4)3(aq) + 3 H2( g), A 25.0-mL sample of a 1.20 M potassium chloride solution is mixed with 15.0 mL of a 0.900 M lead(II) nitrate solution and this precipitation reaction occurs: 2 KCl(aq) + Pb(NO3)2(aq) PbCl2(s) + 2 KNO3(aq), Determine whether each compound is soluble or insoluble. Although low in concentration, some individuals may have extreme skin sensitivities.
