Sodium bicarbonate is an inorganic salt with the chemical formula NaHCO3. This compound is commonly known as baking soda. It is used in cooking, as a cleaning agent or in medicine to relieve heartburn symptoms, for example. You often need to dissolve it before using. Keep in mind that sodium bicarbonate has only a modest solubility in water; only 7.8 grams of the salt can be dissolved in 100 ml of water.
Multiply the volume of the water by 0.078 to calculate the maximum amount in grams of sodium bicarbonate that can be dissolved. For example, you may dissolve up to 23.4 g of the salt in 300 ml of water (300 x 0.078 = 23.4 g)
Weigh the calculated amount of sodium bicarbonate on a scale.
Pour water into a beaker.
Add the sodium bicarbonate to the water in the beaker.
Stir the solution using a spoon until the salt completely dissolves.
