Question

what do you understand the term buffering capacity of the earth and give reason why is it so important/necessary for the survival of living beings?​

Answer 1

Answer:Buffer capacity quantifies the ability of a solution to resist changes in pH by either absorbing or desorbing H+ and OH- ions.  When an acid or base is added to a buffer system, the effect on pH change can be large or small, depending on both the initial pH and the capacity of the buffer to resist change in pH.  Buffer capacity (β) is defined as the moles of an acid or base necessary to change the pH of a solution by 1, divided by the pH change and the volume of buffer in liters; it is a unitless number.  A buffer resists changes in pH due to the addition of an acid or base though consumption of the buffer.  As long as the buffer has not been completely reacted, the pH will not change drastically.  The pH change will increase (or decrease) more drastically as the buffer is depleted: it becomes less resistant to change.

Answer 2

Answer:

Buffer capacity is a quantitative degree of resistance to pH alternate upon the addition of H+ or OH- ions. It is essential for river water to keep a solid pH such that the neighborhood ecosystems are preserved for us to maintain Columbus flourishing.

Explanation:

Buffer capacity is decided via a titration, a method wherein a recognized extent and awareness of a base or acid is brought to the analyte of unknown awareness.  In the analysis, a PASCO explorer GLX data logger with a pH electrode was used to monitor the alternate in pH. Past the buffer region, pH changes appreciably close to the equivalence point. In a laboratory environment, a buffer answer may be created with the aid of using mixing a weak acid with its conjugate base. The ions obviously found in rivers are buffering components that permit the pH of the water to stay stable over time. Buffer capacity of river water may be very essential, commonly necessitating narrow pH ranges which can be important to the survival of maximum organisms.
