What is the pH of a 0.083 solution of HCI

Chemistry
1 answer:
quester [9]3 years ago
8 0

Answer:

The pH is 1.08,  being an acid pH

Explanation:

pH is a parameter used to measure the degree of acidity or alkalinity of a substance. The pH scale ranges from 0 to 14. Values ​​less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral. Mathematically, pH is the negative logarithm of the molar concentration of hydrogen or proton ions (H⁺) or hydronium ions (H₃O⁺).

pH= - log [H⁺]= - log [H₃O⁺]

A strong acid is an acid that completely dissociates into hydrogen ions and anions in solution. This implies that the initial concentration of acid is equal to the final concentration of H₃O⁺. This occurs with acid HCl.

So,  pH is calculated as:

pH= - log (0.083)

pH= 1.08

<u><em>The pH is 1.08,  being an acid pH</em></u>

The destructive force of waves is not felt while they are out at sea, in the open ocean, but it is felt when they do what?
PIT_PIT [208]

Answer: Come Onshore

Explanation:

Sea waves are harmless when present at Sea. However, it becomes DESTRUCTIVE as it travels to the land surface.

Its effects include the sweeping off (erosion) of features, BENEFICIAL soil organisms and the transport of sand and sediment along coastal areas which might include farms, residential houses etc.

Thus, the effects of Sea waves ONSHORE affects the following: agricultural activities

Domestic activities

Environmental balance etc.

If an acid has a Ka of 4.3 × 10-7 and a base has a Kb of 5.6 × 10-4, then what will be true about the salt produced? A. The salt
blsea [12.9K]

If an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.

<h3>What is acid and base constant?</h3>

An acid dissociation constant, Kₐ, is a quantitative measure of the strength of an acid in solution while Kb indicates the high level of dissociation of a strong base.

According to this question, an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴. This shows that the strength of the base is higher than that of the acid.

Therefore, if an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.
