Question for smart people

Answer 1

#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

Answer 2

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
