Using the equation, pH = − log [H+] , we can solve for [H+] as,
− pH = log [H+] ,
[H+] = 10−pH.
Exponentiate both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,
[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M.
Answer:
Anion
Explanation:
Anion is an atom or group of atoms that are negatively charged.
Cations are positively charged
Anode is a positively charged pole that conducts electricity (remember electrolysis)
Cathode is a negatively charged pole that conducts electricity (remember electrolysis too)
