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.
The NO3- anion is the conjugate base of a strong acid (HNO3) and is therefore pH-neutral. 608 Chapter 15 Acids and Bases (c) The CH3NH3+ ion is the conjugate acid of a weak base (CH3NH2) and is therefore acidic.The CH3NH3NO3 solution will be acidic. The NaCHO2 solution will be basic.o determine the overall acidity or basicity of the solution, compare the values of Ka for the acidic cation and Kb for the basic anion. The F-ion is the conjugate base of a weak acid and is therefore basic. basic anionacidic cationNH4F Ka(NH4+) =KwKb(NH3)=1. Since Ka is greater than Kb, the solution is acidic.
