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.

Explain the Law of Conservation of Mass in terms of the atoms and bonds in a chemical reaction.
nasty-shy [4]

Answer:

no matter is destroyed or created, it merely changes form. In terms of atoms and bonds, there will be the same amount of atoms at the beginning of an experiment as the amount of atoms at the end of experiment. All that will have happened, is that during the reaction, bonds will have been broken and formed making new compounds. However, the amount of atoms remains exactly the same because matter can not be created or destroyed

Hope this helps!
