Soda ash is the trade name for sodium carbonate, a chemical refined from the mineral trona or sodium-carbonate-bearing brines (both referred to as natural soda ash) or manufactured from one of several chemical processes (referred to as synthetic soda ash. Universal indicator is not suitable for quantitative analysis and the indicator choices tabulated below are explained via the sets of ph graphs shown further down using graphs a to d the effective ph range of the indicator is where there is sufficient colour change to give a good sharp end–point and can be above or below, but close to the pk. Volumetric methods may be based on acid/base reactions precipitation reactions, complexation reactions and redox reactions table 161 presents a summary of the volumetric methods commonly used for environmental analysis the acid/base methods generally use a strong acid or base as a titrant with methyl orange/red (acid titration) or phenolphthalein (base titration) as the indicator.
