Answer:
[H⁺] = 6.17×10¯⁶ M
Step-by-step explanation:
From the question given above, the following data were obtained:
pH = 5.21
Concentration of Hydrogen ion [H⁺] =?
The pH of a solution is defined by the following equation:
pH = –Log [H⁺]
With the above formula, we can obtain the concentration of Hydrogen ion [H⁺] in the solution as follow:
pH = –Log [H⁺]
5.21 = –Log [H⁺]
Divide both side by –1
–5.21 = Log [H⁺]
Take the antilog of –5.21
[H⁺] = Antilog (–5.21)
[H⁺] = 6.17×10¯⁶ M
Therefore, the concentration of Hydrogen ion [H⁺] in the solution is 6.17×10¯⁶ M
