Answer:
it will gain electrons to fill its outer shell
Explanation:
This element is boron which has 5 electrons.
Ba(OH)2 dissociate according to the following equation
Ba(OH)2----> Ba 2+ + 2OH-
Moles of Ba(OH)2 = 4.02 /171(molar mass of Ba(OH)2 )= 0.0235 moles
by use of mole ratio of Ba(OH)2 to OH- which is 1:2 the moles of OH = 0.0235 x 2=0.047 moles in one liter = 0.047/1000= 4.7 x10^-5
POh=- log (OH-)
that is -log (4.7 x10^-5) = 4.34
Ph= 14 - POH
PH is therefore = 14 - 4.34 = 9.66
