If a sample of a certain solution is determined to have a [h3o+][h3o+] concentration of 4.91×10−44.91×10−4 moles/liter, what is its ph? round off your answer to one decimal place.

Respuesta :

pH scale is used to determine how acidic , basic or neutral a solution is. It can be calculated using the following equation 
pH = -log [H₃O⁺]
hydronium ion concentration has already been given 
[H₃O⁺] = 4.91 x 10⁻⁴ M
pH = -log[4.91 x 10⁻⁴ M]
pH = 3.3
the pH of medium is 3.3
