Determine the identity of the double unknown. NaCl+ KBr 6. Include a few statements justifying your decision. When the double unknown reacted with the AgNO3, the result was a milky white and yellow color. You could see that it was the same colors as NaCL and KBr, therefore we deduced that the double unknown was NaCL + KBr. Table of Results: Single unknown number
