The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
This means that 1 gram of sodium chloride contains approximately 393.4 mg of elemental sodium. [ 94 ] For example, to find out how much sodium chloride contains 1500 mg of elemental sodium (the value of 1500 mg sodium is the adequate intake (AI) for an adult), we can use the proportion:
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, [4] and it is an ingredient in low-sodium baking powders. [5] [6] As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking.
Citric acid is an organic compound with the formula H O C(CO 2 H)(CH 2 CO 2 H) 2. [10] It is a colorless weak organic acid. [10] It occurs naturally in citrus fruits.In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
Pink cubic halite (NaCl; halide class) crystals on a nahcolite matrix (NaHCO 3; a carbonate, and mineral form of sodium bicarbonate, used as baking soda). The halide minerals are compounds in which a halogen (fluorine, chlorine, iodine, or bromine) is the main anion. These minerals tend to be soft, weak, brittle, and water-soluble.
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Diffusion is a property of substances in water; substances in water tend to move from an area of high concentration to an area of low concentration. [26] Blood flows by one side of a semi-permeable membrane, and a dialysate, or special dialysis fluid, flows by the opposite side.
