Your laboratory experiment on "Limiting and Excess Reagents" involves the reaction between aqueous solutions of Cu(NO3)2 and KI to form CuI and I2. The CuI precipitates from the reaction as a solid, and the other products (KNO3 and I2) remain in aqueous solution. In the lab you will vary the relative amounts of each reactant, determining the amount of solid product in each case. In this pre-lab you will explore some features of this reaction.
Write a balanced molecular equation for the overall reaction, using the smallest whole number coefficients, including the states of matter for each reactant and product.
This is the equation I came up with and it is saying it is wrong, please let me know where I made an error! Thank you!
2Cu(NO3)2(aq) + 4KI(aq)?2CuI(s) + I2(aq) + 4KNO3(aq)
