Solution Approximate Acid, Base, or Approximate pH (2, 5, 7, 9, orNeutral? 13) Hydrogen lon Concentration Proton acceptor, donor, or both? HCI NaOH Solution 1) for HCl HCl is strong acid Its approximate pH will be 2 this is acid use: pH = -log [H+] 2 = -log [H+] [H+] = 1*10^-2 M This is proton donor Answer: 2 acid 1*10^-2 M proton donor 2) for NaOH NaOH is strong base pH will be close to 13 use: pH = -log [H+] 13 = -log [H+] [H+] = 1*10^-13 M This is proton acceptor Answer: 13 base 1*10^-13 M proton acceptor .

1. Solution Approximate Acid, Base, or Approximate pH (2, 5, 7, 9, orNeutral? 13) Hydrogen lon
Concentration Proton acceptor, donor, or both? HCI NaOH
Solution
1) for HCl
HCl is strong acid
Its approximate pH will be 2
this is acid
use:
pH = -log [H+]
2 = -log [H+]
[H+] = 1*10^-2 M
This is proton donor
Answer:
2
acid
1*10^-2 M
proton donor
2) for NaOH
NaOH is strong base

2. pH will be close to 13
use:
pH = -log [H+]
13 = -log [H+]
[H+] = 1*10^-13 M
This is proton acceptor
Answer:
13
base
1*10^-13 M
proton acceptor
