Question

a solution with pH =4 is 100 times more acidic than a solution with ph is equal to​

Answer 1

Answer:

ph 6 is the correct answer as log 10=1

and log 100=2

Answer 2

pH would be 6.

Explanation:

• pH means we need to take the negative logarithm of the hydrogen ion concentration.
• A logarithmic change happens in the pH scale.
• A solution with pH = 4, would have a hydrogen ion concentration, $[H^+] = 10^{-4$
• Since it is 100 times more acidic, then the other solution would have hydrogen ions 100 times less.
• So, $[H^+] = \frac{10^{-4}}{100} = 10^{-6$
• Hence, pH $= -log[H^+] = -log[10^{-6}] = -(-6) log10 = 6$
• So, pH would be 6 of the second solution.
