Question

predicted products. Trends of solubility predict that NaNO, is soluble and we w the state of matter. Barium sulfate is insoluble and will receive (s) as the state of matter Balancing the equation and including the states of matter gives the final equation. Na,SO4aq) + Ba(NO3)2(aq) 2NaNOdaq) + BaSO4(s) reaction when given a set of reagents. In today's experiment, you will mix aqueous solutions of Co(NO3)2(aq) + Napo.(aq) products Every General Chemistry student is expected to be able to write a complete precipitation cobalt(II) nitrate and sodium phosphate. As part of your pre-lab preparation, you should complete equation 6 by predicting the products with states of matter, and balance the equation. While cobalt can take on various charges, as most transition metals do, equation 6 is not a redox reaction and the charge of the cobalt ion is consistent from reactant to product. In today's experiment, you'll learn new techniques such as vacuum filtration and the proper use of a graduated pipet. You'll also be asked to calculate the percent yield for each of your precipitation reaction trials. Based upon the molar amounts of Co(NO;)h and NayPO4 used, you'll need to determine the limiting reagent, calculate the theoretical yield of the isolated precipitate, and finally calculate the percent yield for the formation of the precipitate. actual yield theoretical yield % yield= Calculations Prior to doing any calculations, you must write the complete balanced chemical equation 5 6

Explanation / Answer

Hi Friend,i can only balance the chemical reaction, since before predicting actual and theoretical yields i need how much reactants you have initially taken during the precipitation reaction and finally how much product you have been isolated. Without this information no body can calculate all these calculations.

Co is in +2 state, from given info it should not change its oxidation state since this is not a redox reaction, it's a precipitation reaction. Na is in +1 state. Both these should reflect in products also. PO43- still appear as intact.

Balanced equation: 3 Co(NO3)2(aq) + 2 Na3PO4(aq) Co3(PO4)2(s) + 6 NaNO3(aq)
