Determine the percent yield for the reaction between 45.9 g of
NaBr and excess chlorine gas to
produce 12.8 g of NaCl and an
unknown quantity of bromine gas.​

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
