That would be a depression..
The statement that is not true regarding the pH scale would be the final one. As the concentration of hydroxide ions in a corresponding solution increases, the pH would increase, as the solution becomes more basic and not as acidic. The pH values from 0-6 account or characterize a solution to be acidic, while from 8-14 would be basic. Increase in hydroxide will increase the pH from original value.

Answer:
HI& HNO3= strong acid
H2CO3 &HF= weak acid
LiOH & Ba(OH)2= strong base
CH3NH2= weak base
NH4Cl = weak acid solution
Na3PO4 = weak base solution
Explanation:
HI& HNO3= strong acid because they can dissociate completely producing free Oxonium ions
H2CO3 &HF= weak acid because there dissociate partly in Solution
LiOH & Ba(OH)2= strong base because LiOH is a group one alkali which dissociate completely and Ba(OH)2 a group 2 alkali which dissociate completely as well
CH3NH2= weak base because in solution it dissociates partly forming NH4+ ion
NH4Cl = weak acid solution because it is a salt of strong acid and weak base
Na3PO4 = weak base solution
Because it's a salt of strong base and weak acid
M(O)= 16 g/mol
M(H)=1 g/mol
m(O)/m(substance)
1) 16/17
2)16/18
3) 16/19
4) 32/34=16/17
1) and 4) give the same answers, and 16/17 are the greatest fraction, so greatest % oxygen by mass also.
The answers should be 1) and 4).
