A solution has a [H+] of 0.20 M. Find the pH of this solution.

Chemistry

1 answer:

Rus_ich [418]2 years ago

4 0

The pH of this solution : 0.699

<h3>Further explanation </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.

A solution has a [H+] of 0.20 M, so [H⁺]=0.2

$\tt pH=-log[H^+]\\\\pH=-log[0.2]\\\\pH=1-log~2\\\\pH=0.699$

Select the correct answer.

Minchanka [31]

Answer:

A. it is the lowest at low temperatures

Explanation:

It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.

The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.

Kinetic energy is directly proportional to the temperature of a substance.
The higher the temperature, the more the kinetic energy of the molecules within a system.
At low temperature, kinetic energy is the lowest.
At the highest temperature, kinetic energy is the highest

aalyn [17]

<h3>Molar mass of Potassium Nitrate:-</h3>

$\\ \large\sf\longmapsto KNO_3$

$\\ \large\sf\longmapsto 39u+14u+3(16u)$

$\\ \large\sf\longmapsto 53u+48u$

$\\ \large\sf\longmapsto 101u$

$\\ \large\sf\longmapsto 101g/mol$

Now

$\boxed{\sf No\:of\:moles=\dfrac{Given\:mass}{Molar\:mass}}$

$\\ \large\sf\longmapsto No\:of\:moles=\dfrac{0.565}{101}$

$\\ \large\sf\longmapsto No\:of\:moles=0.005mol$

We know

$\boxed{\sf Molarity=\dfrac{Moles\:of\:solute}{Vol\:of\:Solution\:in\:L}}$

$\\ \large\sf\longmapsto Molarity=\dfrac{0.005}{\dfrac{250}{1000}L}$

$\\ \large\sf\longmapsto Molarity=\dfrac{0.005}{0.250}$

$\\ \large\sf\longmapsto Molarity=0.02M$

Answer:

occur if two of the ions form an insoluble ionic compound, which precipitates out of solution

Explanation:

When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.

Elden [556K]

<span>At constant temperature and moles, the answer can simply becomes P1V1 = P2V2. The original sample is 760 torr and 5.00 l, and was then compressed to 3.00 l. (760 torr)(5.00 l ) = (3.00 l)(X torr), X = 1270 torr. The new pressure exerted by helium on its container is 1270 torr.</span>
