The amount of water vapor present at equilibrium is then F12:7 1atm × (30.6 dm3 ) (130 Torr) × 760 Torr pV = = 0.193mol n= RT (0.08206 dm3 atm K −1 mol−1 ) × (330.2 K) This is a substantial fraction of the original amount of water and cannot be ignored. The reason KBR is neutral is because when reacting with H2O you form, KOH and HBR, hence they cancel each other out, and you are left with a neutral pH of solution of 7, nothing contributed to the pH of pure water.

A mixture of ammonia and ammonium chloride is basic because the K b for ammonia is greater than the K a for the ammonium ion. It is a buffer because it also contains the salt of the weak base. If we add a base (hydroxide ions), ammonium ions in the buffer react with the hydroxide ions to form ammonia and water and reduce the hydroxide ion concentration almost to its original value:When we dissolve NaCl in water, we get sodium cations and chloride anions. These are, respectively, the conjugate acid of the strong base NaOH and the conjugate base of the strong acid HCl. That means sodium and chloride ions are very weak acids a...

Carbonic acid (H 2 CO 3) is an ingredient in soft drinks. A decomposition reaction takes place when carbonic acid breaks down to produce water (H 2 O) and carbon dioxide (CO 2). This occurs when you open a can of soft drink and some of the carbon dioxide fizzes out. The equation for this reaction is: High water soluble levels of potassium cause damage to germinating seedlings, inhibits the uptake of other minerals and reduces the quality of the crop.
