1 mole NaOH/700ml=Molarity=.00142M NaOH

Error. Doesn't it seem weird that adding 200 mL to a 500 mL solution would reduce the concentration of NaOH from 2M all the way to .00142M? That is like dilution by a factor of over a 1000. I wonder if it has something to do with units...   

Did 1/700 instead of 1/.7...which gives 1.42M,

pardon

In a report you write down your results you observed, after confirmation and verifying. If you find pH 15 then you write this down.

ok pH = 15 mean some thing to me as a chemist  but for those who know traces about chemistry how can them interpret it

Strong base shows concentration close to 10 M.

i dont mean this number specifically , what i want to say is the unusual results i can understand it but  who dont has chemistry  background cant .

So what?

i just want to say what happened with me when reporeted such results
