Answer: Option (3) is the correct answer.

Explanation:

A condition where a gas if held at high temperature and low pressure then it will behave like an ideal gas.

This is because at high temperature gases will have high kinetic energy. Therefore, they will be in rapid motion and forces of attraction between them will be minimum.

Also, at low pressure gases will not come closer to each other and thus molecules of gas will move freely. Hence, the gas will behave like an ideal gas.

Thus, we can conclude that under conditions of high temperature and low pressure carbon dioxide gas will behave most like an ideal gas.

You need to prepare 1 L of the citric acid/citrate buffer. You have chosen to use Method 1 (see lab presentation). Calculate the
prisoha [69]

Answer:

3.11 is the pH of the buffer

Explanation:

The pH of a buffer is obtained using H-H equation:

pH = pKa + log [Conjugate base] / [Weak acid]

<em>Where pH is the pH of the buffer, pKa = -log Ka = 3.14 for the citric buffer and [] could be taken as the moles of each species.</em>

The citric acid,HX (Weak acid), reacts with NaOH to produce sodium citrate, NaX (weak base) and water:

HX + NaOH → H2O + NaX

That means the moles of NaOH added = Moles of sodium citrate produced

And the resulitng moles of HX = Initial moles - Moles NaOH added

<em>Moles HX and NaX:</em>

Moles NaOH = 0.100L * (0.65mol / L) = 0.065 moles NaOH = Moles NaX

Moles HX = 0.300L * (0.45mol / L) = 0.135 moles HX - 0.065 moles NaOH = 0.070 moles HX

Replacing in H-H equation:

pH = 3.14 + log [0.065mol] / [0.070mol]

pH = 3.11 is the pH of the buffer
