PH measures the concentration of hydrogen ions on the log 10 scale. Thus, a pH 5 solution has 2 order of magnitude difference from that of pure water, which has a pH of 7.
Therefore,
. A solution of pH 5 has 100 times more hydrogen ions that that of pure water.
Therefore,
Answer:
Explanation:
From the information given:
Step 1:
Determine the partial pressure of each gas at total Volume (V) = 4.0 L
So, using:
Now, to determine the final pressure using different temperature; to also achieve this, we need to determine the initial moles of each gas.
According to Ideal gas Law.
For moles N₂:
For moles of Ar:
Finally;
The final pressure of the mixture is:
P = 2.217 atm
P ≅ 2.24 bar
