The resulting solution made from the combination of 50ml of 1.0M LiOH with 50ml of 1.0M HBr will be identical in all respects to 100ml of:
A)0.5M LiBr
B)1.0M LiBr
C)2.0M LiBr
D) a saturated solution of LiBr (s)
Picked B but the answer was A. I reasoned that
(MV)LiOH +(MV)HBr = (MV)LiBr so 1(50) + 1(50) = (100)M Libr so M = 1M LiBr
I don't understand why the answer is .5M LiBr, can someone please explain?
