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.
This means that $\ce{Cl-}$ is a really weak base, meaning that it is pretty bad at pulling protons from molecules. Also water is the conjugate acid of NaOH, which is a strong base. This means that water is a really weak acid, meaning that it is also pretty bad at kicking out one of its protons. This means that in this reaction, barely any of the products will react and you will mainly end up with NaCl and water. As you can see in both reaction the equilibrium will favour the weak acid and base as they aren't able to react that well together. This effect can also be explained by using equilibrium constants but I won't go into that.
