the pH of solution is 5.0. if its hydrogen ion concentration is decreased 100 times, the solution then will be acidic or basic or neutral.??? Please explain by using the pH formula.. don't give the answer. Please it's urgent...

The pH of a solution can be calculated by determining the concentration of Hydrogen ions (H⁺).
The formula for relating Hydrogen ion concentration with the pH of the solution is given as log[H⁺] = - pH.
So, based on this equation, pH = (-1) log [H⁺].
So, [H⁺] = anti-log (- pH)
Therefore, if pH is 5.0 and the H⁺ ions decrease, then the pH value will increase. This means that the pH of the solution will drift towards the neutral to the basic range, depending on the decrease in the H⁺ ion concentration.
This result is in coordination with the theory which explains that the pH value will drop as the H⁺ ion concentration increases and the pH value will increase as the H⁺ ion concentration decreases.
