An industrial chemist studying bleaching and sterilizing prepares a hypochlorite buffer using 0.500 M HClO and 0.500 M NaClO. (Ka for HClO = 2.9 × 10−8)

Find the pH of 1.00 L of the solution after 0.045 mol of NaOH has been added

The correct name for n3-ion should be azide.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

C. definite shape, definite volume. that is a solid.

Naoh + hbr -> nabr (salt) + h2o ca (oh)2 + 2hbr - - - > ca (br)2 + 2h2o
