Aniline (c6h7n) has a pkb = 9.4. what are the dominant species present in water if the ph is held constant at ph = 8?
anzhelika [568]

The dominant species present in water if the ph is held constant at ph = 8 is C_{6}H_{7}N,H_{3}O^{+}.

<h3>What is ph?</h3>

The pH scale is used in chemistry to determine whether an aqueous solution is basic or acidic. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave. The negative log base 10 of the hydronium concentration is used to define pH. The pH is a logarithmic indicator of how many hydrogen ions are present in a solution. Since pH is measured on a log scale, a pH increase of 1 equates to a 10x increase in the concentration of H+ ions.

According to the wave- mechanical model of the atom , an orbital is a region of the most probable location of ? ( please provide
notka56 [123]
An orbital is the most probable location of an electron. This is because you can't pinpoint the exact location of an electron because as soon as you do it will have moved again, so orbitals are used to find the probability of where a certain electron is.
