pH aqueous solutions

pH aqueous solutions : In most solutions at most values of pH, Si4+ is dissolved as a hydroxocomplex.

Si(OH)4 is the formula that best represents the nature of the complex, but H4SiO4 (silicic acid) is commonly used to indicate that the complex can surrender H+ ions and thus behave as an acid.

The pH of an aqueous solution is the measure of how acidic or basic it is. The pH of an aqueous solution can be determined  and calculated by using the concentration of hydronium ion concentration in the solution.    The pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater than 7 is then considered basic. Acidic solutions have high hydronium concentrations and lower hydroxide concentrations. Basic solutions have high hydroxide concentrations and lower hydronium concentrations.
