Final answer:
Processing P\Solution is formulated to maintain a basic pH, meaning its hydronium ion concentration is less than pure water's concentration of 1 × 10-7 M, indicating a pH above 7.
Step-by-step explanation:
To determine whether Processing P\Solution is formulated to be acidic, neutral, or basic, we need to look at the concentration of hydronium ions ([H3O+]) in the solution. An acidic solution has a higher concentration of hydronium ions than pure water and a pH < 7.
A neutral solution has an equal concentration of hydronium ions compared to pure water, which is 1 × 10-7 M, corresponding to a pH of 7.
Lastly, a basic solution, also referred to as alkaline, has a lower concentration of hydronium ions than pure water and a pH > 7. Therefore, if Processing P\Solution is designed to maintain a basic pH, through its formulation it must ensure that the concentration of hydronium ions is less than 1 × 10-7 M.
For example, milk of magnesia with a pH of 10.5 is basic, while wine with a pH of 3.0 is acidic, and pure water having a pH of 7 is neutral. This is based on the relationship between pH value and hydronium ion concentration, with the pH being the negative logarithm of the hydronium ion concentration (-log[H3O+]).
