A)

  • pH⇢ 9.50
  • pOH⇢14 - pH
  • pOH⇢ 14 - 9.50
  • pOH⇢4.50

B)

  • 9.50 = - log [H3O+]
  • -9.50 = log [H3O+]
  • [H3O+] = 10^-9.50
  • [H3O+] = 3.16 x 10^-10 M

C)

  • The solution is basic in nature as it's pH >7

#a

  • pH+pOH=14
  • pOH=14-9.50
  • pOH=4.50

#b

[H+] be x

  • -logx=9.50
  • logx=-9.5
  • x=10^{-9.5}
  • x=3.2×10^-10M

#c

basic as pH is 9.5>7
