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.

A functional group is a specific arrangement of atoms in an organic compound that is acmpavle if characteristic reactions
STatiana [176]

Explanation:

(a) a functional group is a special group of atoms or bonds in a compound that is responsible for the chemical reactions, behavior, and characteristics of that compound. (b) Functional group is present in both the compound is alcohol (-OH).

Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples are alcohols, amines, carboxylic acids, ketones, and ethers.

Key Points

Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form.

Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity.

Functional groups can be used to distinguish similar compounds from each other.

Key Terms

functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class.

functionalization: Addition of specific functional groups to afford the compound new, desirable properties.

A 25.0 mL sample of a solution of an unknown compound is titrated with a 0.115 M NaOH solution. The titration curve above was ob
Mnenie [13.5K]

Answer:

Weak acid

Explanation:

A titration curve is a graphical description of the change in pH of the solution in the conical flask as the reagent is added from the burette. A titration curve can be plotted for the different kinds of acid and base titrations. The volume of the titrant is always plotted as the independent variable and the pH of the solution as the dependent variable. The equivalence point is read off from the titration curve. A titration curve is very important because it shows the pH at various points during the titration.

A weak acid/strong base titration leads to an equivalence point above 7. From the question, we were told that the pH at equivalence point lies around 8. Hence the unknown substance must be a weak acid.

Is Lithium oxide type I or type II ?
AnnZ [28]

Answer:

1 is the answer

Explanation:

The ionic formula for Lithium Oxide is Li2O . Lithium is an Alkali Metal in the first column of the periodic table. This means that lithium has 1 valence electron it readily gives away in order to seek the stability of the octet.
