As there is almost one-third of the oxygen available at the summit of K2 as there is on sea level. It is covered with glaciers and snow covered mountains that rise from its base at about 15000 feet on the Godwin Austen Glacier, a tributary of the Baltoro Glacier. The mountain was first discovered and measured in 1856 by Col. T.G.
The reason NaCl doesn't change the pH of a solution is because the cation (Na+) and anion (Cl-) that are produced when NaCl is dissolved are really weak acids and bases. We know this because their conjugate acid and base partners are really strong acids and bases. The conjugate base of Na+ is NaOH and the conjugate acid of Cl- is HCl. Look how tiny those dissociation constants are. Those dissociation constants tell us that the reaction will lie very far to the left.
1 HCl/Cl- are called a Bronsted-Lowry acid-base pair. Cl- is referred to as the conjugate base of the acid HCl. Notice that the acid-base pair differ by only a proton. Also H2O-H3O+ are also an acid-base pair. H3O+ is the conjugate acid of the base H2O.
