    Chemical

    Sodium benzoate will react with sodium hydroxide to produce benzene: 1. C6H5COONa + NaOH → C6H6 + Na2CO3 Small amounts of biphenyl and benzophenonewill also be produced as side products. Ascorbic acidwill also reduce the salt to benzene under certain conditions.

    Physical

    Sodium benzoate is a white hygroscopic compound, with a characteristic smell. It has a solubility in water of 62.7 g/100 ml at standard conditions. Sodium benzoate is also soluble in liquid ammonia and pyridine. It is poorly soluble in most alcohols, like methanol and ethanol.

    Safety

    Sodium benzoate has low toxicity to humans, and recent studies have shown to have some beneficial effects, in preventing Alzheimer and Parkinson's, though the results aren't conclusive so far. Cats however, have a significantly lower tolerance against benzoic acid and its salts, than rats and mice. If consumed with ascorbic acid, it may yield benzene, which is carcinogen, phenomenon observed in drinks containing sodium benzoate as preservative. However the levels of benzene obtained are extre...

    Storage

    Sodium benzoate should be stored in closed bottles, as it's slightly hygroscopic, though keeping it in a dry chamber is sufficient.

    Disposal

    Sodium benzoate has low toxicity and doesn't require special disposal. Discard it as you wish.

    Jun 19, 2019 · The molar mass of an element is found on the periodic table, and it is the element's atomic weight in grams/mole (g/mol). If the mass of a substance is known, the number of moles in the substance can be calculated. Converting the mass, in grams, of a substance to moles requires a conversion factor of (one mole of substance/molar mass of substance).
