What effect does the concentration of H ions have on the nature of the solution?

Answer 1

pH is -log10[H3O+]; the negative logarithm (with base 10) of the hydronium concentration (hydrogen ions do not float around on their own. Instead they attach to a water molecule and become a hydronium ion).

Answer 2

The concentration of H+, in chemical notation, [H+], ions determines the acidity of the solution. When we measure [H+] relative to the other constituents of the solution, a wide range of values are possible (around 1*1014). For convenience, the pH scale was developed where the pH of a solution is given by

pH=-log([H+])

This reduces values to the familiar 1 to 14 scale, with 1-6 as basic solutions, 7 as neutral (water), and 8-14 as acidic solutions.

Answer 3

The pH is actually simply the measure of the concentration of these ions. Specifically, it's the presence of these ions in relation to hydroxide.

Answer 4

as the concentration of H atoms increases, the pH decreases.

pH=-log[H]

or, pH is equal to the negative logarithm of the concentration of hydrogen atoms

Answer 5

The presence of H ions in a solution can cause a reaction with magnesium to release Hydrogen gas.

Answer 6

It will cause the solution to become acidic in pH.
