Aqueous solution of phosphoric acid with a density oflg mL-1 containing 0.05% by weight of phosphoric acid is used to impart tart taste to many soft drinks. Phosphate ion is an inteife ring radical in qualitative analysis. It should be removed for analysis beyond third group of qualitative analysis
the basicity of phosphoric acid is:
Chemistry-General
Chemistry-
The product of the concentrations of the -ions of an electrolyte raised to power of their coefficients in the balanced chemical equation in the solution at any concentration. Its value is not constant and varies with change in concentration. Ionic product of the saturated solution is called solubility product ![K subscript s p end subscript](data:image/png;base64,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)

The product of the concentrations of the -ions of an electrolyte raised to power of their coefficients in the balanced chemical equation in the solution at any concentration. Its value is not constant and varies with change in concentration. Ionic product of the saturated solution is called solubility product ![K subscript s p end subscript](data:image/png;base64,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)
i) When
' the solution is just saturated and no precipitation takes place
ii) When
the solution is unsaturated, and precipitation will not take place
iii) When
' the solution is supersaturated, and precipitation takes place

An acid-base titration consists of the controlled addition of a dissolved base to a dissolved acid (or the reverse). Acid-base react rapidly to neutralize each other. At the equivalence point, enough titrant, the solution being added, has gone into make the chemical amounts of the acid and base' exactly equal. The pH of a titration changes every time a drop of titrant is added, but the rate of this change varies enormously. A titration curve, graph of pH tis a function of the volume of titrant, displays in detail how the pH changes over the course of an acid-base titration. Significantly, the pH changes most rapidly near the equivalence point. The exact shape of a titration curve depends on the

acid and base
