Stability    
1. It will not decompose if used and stored according to specifications.

2. 187g dissolved in 100g water at 25ºC, can chelate with alkaline earth metal and heavy metal ions. Soluble in water, insoluble
in ethanol. Aqueous solution is alkaline, the solubility is 187g in 100g of water at 25ºC, the concentration of 1% aqueous solution
pH=10.2. Potassium pyrophosphate has all the properties of other condensed phosphates.

3. Hygroscopicity and deliquescence are great. Solubility 187g in 100g water (25ºC). Insoluble in ethanol. Concentration of 1%
aqueous solution pH 10.2. α-type (high-temperature type) and β-type (low-temperature type) two variants. β-type in 500 ° C converted
to α-type. It is difficult to decompose when boiling aqueous solution alone, but can be hydrolysed when other acids or bases are present.
