BIO 135 Lab Report: Cations and anion reactions Cations and anion reactions II. Introduction • Reaction between cations and anions will be examined in this lab. The resulting precipitate is indicative of the reaction that occured. • In our lab a lead nitrate solution, Pb(NO3)2 will be mixed with a solution of potassium chromate, K2CrO4 , a yellow precipitate will forms. This precipitate must be a combination of K+ or Pb2+ cation and CrO4 2- or NO3 2- anion. Since most po...
