Acids, Bases and pH Part One What is pH? • A measure of Hydronium Ion (H 3 O + ) concentration in solution • Measured on a scale ranging from 0 – 14 –Acid = <7 –Base = >7 –Neutral = 7, example: pure water What is an Acid? • A substance that prod...
II. pH of monoprotic dilute weak acids and bases For weak monoprotic acids, an equilibrium is established between the acid and products of dissociation: HA+H2O⇌H3O++A− The equilibrium constant is defined as: construct a system of equations using material balance and charge balance: ...

In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.Figure 1. The pH scale measures the concentration of hydrogen ions (H+) in a solution.The stronger the acid, the more readily it donates H+. For example, hydrochloric acid...

Interestingly, biocrusts (largely alkaline with pH 6.8–8.218) that mainly provide fixed N to desert soils also emit large amounts of HONO18,19, known to form under acidic conditions because acid–base dissociation constant of HONO is pKa = 3.321,22. This puzzle motivated our investigation...
