GREYUIT [131]3 years ago

The question is incomplete; the complete question is;

Why will the conjugate base of a weak acid affect pH? Select the correct answer below: O it will react with hydroxide

O it will react with water

O it will react with hydronium

O none of the above Content attribution

Answer:

O it will react with hydronium

Explanation:

If we have a weak acid HA, the weak acid ionizes as follows;

HA(aq) ----> H^+(aq) + A^-(aq)

A^- is the conjugate base of the weak acid.

H^+ interacts with water to form the hydronium ion as follows;

H^+(aq) + H2O(l) ----> H3O^+(aq)

The pH=[H3O^+]

But the conjugate base of the weak acid reacts with this hydronium ion thereby affecting its concentration and the pH of the system as follows;

A^-(aq) + H3O^+(aq) ------> HA(aq) + H2O(l)

Classify each process by its individual effect on the entropy of the universe, s. hydrogen peroxide slowly decomposing into wate
Jobisdone [24]
Hydrogen Peroxide slowly decomposing into water and oxygen increases the entropy of the universe. Any reaction of a system always increases the degree of the orderliness of the universe. Decomposition is one of the best examples of increasing the entropy. This is when substance is broken down further to elements or other compounds.

What type of chemical bond holds the na+ and cl- ions together in table salt?
fredd [130]

<em>The bond between Na + and Cl- ions is an ionic bond</em>

<em>To achieve stability, atoms with low ionization energy such as Na atoms will release electrons and bind to atoms with high-affinity energy such as Cl atoms</em>

\boxed{\boxed{\bold{Further~explanation}}}

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by forming shared ions or electron pairs

Atoms with high ionization energy and atoms that are difficult to draw electrons will form bonds with shared electron pairs (electrons can be from one atom or two atoms attached)

In forming ions, atoms will release or attract electrons

Ion bonds occur because atoms that have low ionization energy (easily release electrons) form a + ion, and these electrons are bound by atoms that have large affinity energy (easily pulling electrons)

Generally, ionic bonds occur in metal and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity

In Na atoms, to achieve stability, Na will release one electron so that it has an electron configuration like noble gas Ne

Na: 2 8 1

Ne: 2 8

so that it becomes a Na + ion

While the Cl atom will bind one electron, so it has an electron configuration like noble gas Ar

Cl: 2 8 7

Ar: 2 8 8

So that it becomes a Cl- ion

Finally, there will be an attractive attraction between positive ions and negative ions and NaCl is formed

So the bond between Na + and Cl- ions is an ionic bond
