0.224g sample the contained only bacl2 and kbr required 19.7ml of 0.1M agn03 to reach the end point. Calculate the percent of each compound present in the sample.

Steve want you step by step for me.

• ?? Dr Bob ?? -

Not sure. What's the reaction?

• To Steve -

BaCl2 + 2AgNO3 ==> 2AgCl + Ba(NO3)2 and
KBr + AgNO3 ==> AgCl + KNO3

g BaCl2 + g KBr = 0.224g
2*mols BaCl2 + mols KBr = mols AgNO3
