Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
Hello!
A solution of a weak base and its conjugate acid act as a better buffer than does a solution of a weak base alone because <span>A solution of a weak base alone has no acid present to absorb added base.</span>
If an acid (In this case HCl) is added to a buffer or a weak base solution, the following reaction happens:
HCl + A⁻ → HA + Cl⁻
In this way, the addition of acid is neutralized by the base.
If a base is added (In this case NaOH), only a solution of a weak base and its conjugate acid can react in the following way:
NaOH + HA → NaA + H₂O
So, a solution of only a weak base can resist the addition of acids but not bases, so it isn't a good buffer.
Have a nice day!
