Answer:

The answers are in the explanation.

Explanation:

Analyze the form of H2O: The water molecule is composed of an oxygen atom, linked to two hydrogen atoms. The oxygen atom shares one pair of electrons with each hydrogen atom, leaving two pairs of free electrons in the oxygen without sharing.

What is the shape of the H2O molecule? The pairs of unshared electrons exert a repulsion, so the molecule acquires the angular shape.

Is it symmetrical? The H2O molecule is asymmetric due to free electron pairs.

Does this mean that the H2O molecule is polar or non-polar? Does this mean that the molecule is polar, as the uneven distribution of electrons gives it a slightly negative charge near the oxygen atom and a slightly positive charge near the hydrogen atoms.

In a 0.20 M solution, a weak acid is 3.0% dissociated.(a) Calculate the [H₃O⁺] , pH , [OH⁻], and pOH of the solution.

marin [14]

H₃O⁺ = $6.0$ × $10^{-3}$

OH = $1.7$ × $10^{-12}$

pH = 2.22

pOH = 11.78

The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.

The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.

⇒pH = -log( $a_{H+}$ )

Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
