Question

The table below is an analysis of the water in natural loch in Scotland

colour hazen units:12.5

TDS:65 mg/l, CL:15 mg/l, SO4 :28.2, Na 6.0 mg/l, K:.83 mg/l,Ca:12.03,Mg:1.701 mg/l

what's your comment briefly on:

1-whether the oxygen content of the water would be expected to be higher / lower in winter compared to summer ?

2-whether the oxygen content would be expected to be higher / lower than on seawater at the same temperature

Answer 1

You're asking people to do your analytical chemistry homework for you. You will not get much help this way. If you gave an answer and asked for feedback people might help you, or if you asked for an explanation of an idea. But this is just your homework, so you do it.
