Answer: Option (B) is the correct answer.
Explanation:
An aqueous solution that consists of a mixture of weak base and its conjugate acid or a weak acid and its conjugate base is known as a buffer.
When we add a strong acid or base into this mixture then the change in pH of this mixture is very small.
In a buffer solution, pH depends on the ratio of concentration of base divided by concentration of acid.
It is known that for a given temperature, the value of remains constant.
Therefore, relation between pH and will be as follows.
pH =
Thus, we can conclude that the purpose of an acid-base buffer is to maintain a relatively constant pH in a solution.
Answer:
the pressure of a gas is directly proportional to its volume.
Explanation:
Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Where;
P1 is the original pressure.
P2 is the final pressure.
V1 is the original volume.
V2 is the final volume.
This ultimately implies that, ventilation which is typically governed by Boyle's Law, which states that at a constant temperature the pressure of a gas is directly proportional to its volume.
