Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.

What is the pH of a 0.00125 M HCl solution?

timofeeve [1]

Answer:

$pH=2.9$

Explanation:

Hello,

In this case, the pH is computed by:

$pH=-log([H^+])$

Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:

$pH=-log(0.00125)\\\\pH=2.9$

Regards.
