Calculating the expected pH of the buffer solution: Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the
ser-zykov [4K]

Answer:

pH=4.77

Explanation:

From the question we are told that:

pKa for Acetic Acid pK_a= 4.77

Therefore

For Equal Concentration of acetic acid and acetatic ion

CH_3COOH=CH_3COO^-

Generally the Henderson's equation for pH value is mathematically given by

pH=pK_a+log\frac{base}{acid}

pH=4.77+log\frac{CH_3COO^-}{CH_3COOH}

pH=4.77+log1

pH=4.77

aleksklad [387]

Answer:

The resonance forms of O3 are attached as an image.

Explanation:

A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.

The given compound is ozone, having the chemical formula  

O3 = 6 electrons * 3 = 18 electrons

O → prefers to have a complete their octet

The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.
