1 answer:
Answer:
Pressure, volume and temperature
Explanation:
<u>Ideal gas law</u>
where
p= pressure,
V= volume,
n= number of moles,
R= universal gas constant
T= temperature
_____
The ideal gas law is made up of the 4 laws below:
1) Avogadro's law
• The volume of a sample of gas is directly proportional to the number of moles of gas in the sample at constant temperature and pressure
• V∝ n
2) Boyle's law
• The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature
• p∝ 1/V
3) Charles' Law
• The volume of gas is directly proportional to its absolute temperature at constant pressure
• V∝ T
4) Gay-Lussac's Law
• The pressure of gas is directly proportional to its absolute temperature at constant volume
• p∝ T

pH of 0.048 M HClO is 4.35.
<u>Explanation:</u>
HClO is a weak acid and it is dissociated as,
HClO ⇄ H⁺ + ClO⁻
We can write the equilibrium expression as,
Ka =
Ka = 4.0 × 10⁻⁸ M
4.0 × 10⁻⁸ M =
Now we can find x by rewriting the equation as,
x² = 4.0 × 10⁻⁸ × 0.048
= 1.92 × 10⁻⁹
Taking sqrt on both sides, we will get,
x = [H⁺] = 4.38 × 10⁻⁵
pH = -log₁₀[H⁺]
= - log₁₀[ 4.38 × 10⁻⁵]
= 4.35
