What is the ph of a buffer solution that is 0.172 m in hclo and 0.131 m in naclo? hint: the ka of hclo is 3.8 x 10-8.
nata0808 [166]

The pH of the buffer solution is 7.30 for 0.172 m in Hypochlorous acid and 0.131 m in Sodium hypochlorite.

<h3>What is a buffer solution?</h3>

A weak acid and its conjugate base, or a weak base and its conjugate acid, are mixed together to form a solution called a buffer solution, which is based on water as the solvent. They do not change in pH when diluted or when modest amounts of acid or alkali are added to them. A relatively little amount of a strong acid or strong base has little effect on the pH of buffer solutions. As a result, they are employed to maintain a steady pH.

According to the question:

Ka = 3.8×10⁻⁸

pKa = - log (Ka)

= - log(3.8×10⁻⁸)

= 7.42

pH = pKa + log {[conjugate base]/[acid]}

= 7.42+ log {0.131/0.172}

= 7.302

The weight of an object on a planet depends not only on its mass but also on its distance from the planets center this table lis
Korvikt [17]

You just pointed out that the gravitational force also depends
on the distance from the planet's center. The radius of Uranus
is about 4 times the Earth's radius.  That fact alone means that
the gravitational force on the surface is 1/4² = 1/16 its value on
Earth's surface.  So increasing the planet's mass by a factor of
14 doesn't compensate for the 1/16 reduction, and the gravitational
force on Uranus is less than on Earth.
