Respuesta :
this is formula to find pH. -log[H^+]
now press calculator -log[4.7×10^11] and you will get 10.33

Answer:
10.33
Explanation:
pH is negative logarithm of the hydrogen ion concentration.
Given, hydronium ion concentration = 4.7 x 10⁻11
pH = - log[H₃O⁺] = - log(4.7 x 10⁻11) = 10.33
A pH below 7.0 means the solution is acidic. Neutral pH is at 7.0. For pH above 7.0 the solution is basic
