From the Henderson-Hasselbalch equation, explain how the ratio [Al/[HA] changes with changing pH
Kryger [21]

Answer:

The ratio [A-]/[HA] increase when the pH increase and the ratio decrease when the pH decrease.

Explanation:

Every weak acid or base is at equilibrium with its conjugate base or acid respectively when it is dissolved in water.

HA + H_{2}O ⇄ A^{-} + H_{3}O^{+}

This equilibrium depends on the molecule and it acidic constant (Ka). The Henderson-Hasselbalch equation,

pH = pKa + Log \frac{[A^{-}]}{[HA]}

shows the dependency between the pH of the solution, the pKa and the concentration of the species. If the pH decreases the concentration of protons will increase and the ratio between A- and AH will decrease. Instead, if the pH increases the concentration of protons will decreases and the ratio between A- and AH will increase.

What phrase from the Preamble justifies a law like the Affordable Care Act?
Alexandra [31]
<span>The Affordable Care Act which was instated during Barack Obama´s presidency and is sometimes known as Obamacare is justified by the phrase ¨for the general welfare¨ in the Preamble. This concept can be defined as holding the US government responsable for providing care for all people, not just a few elites. Therefore the Affordable Care Act, which aims to increase access to healthcare to all Americans is adhering to this phrase.</span>
