Calcium bicarbonate, also called calcium hydrogencarbonate, has the chemical formula Ca(HCO 3) 2. The term does not refer to a known solid compound; it exists only in aqueous solution containing calcium (Ca 2+), bicarbonate (HCO − 3), and carbonate (CO 2− 3) ions, together with dissolved carbon dioxide (CO 2).
When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.
3 Bicarbonate: H 2 CO 3 Carbonic acid: CO 2− 3 Carbonate ion: HCO − 3 Bicarbonate: Br − Bromide ion HBr Hydrogen bromide: HPO 2− 4 Hydrogen phosphate: H 2 PO − 4 Dihydrogen phosphate ion Cl − Chloride ion HCl Hydrogen chloride: H 2 O Water: H 3 O + Hydronium ion Nitrite ion Nitrous acid
The amount of potassium deficit can be calculated using the following formula: K deficit (in mmol) = (K normal lower limit − K measured) × body weight (kg) × 0.4 Meanwhile, the daily body requirement of potassium is calculated by multiplying 1 mmol to body weight in kilograms.
Isang puting solido ang sodium bicarbonate na malakristal, ngunit pinong pulbos ang kadalasang itsura nito. Mayroon itong bahagyang maalat, alkalinang lasa ng kahawig sa sodium carbonate. Nahcolite ang tawag sa anyong likas na mineral nito. Isa itong bahagi ng mineral na natron at masusumpungan ito na nakatunaw sa maraming bukal. [9]
Intravenous sodium bicarbonate is contraindicated in patients who are losing chloride, such as by vomiting. [9]Because of its sodium content, intravenous sodium bicarbonate should be used with great care, if at all, in patients with congestive heart failure and severe chronic kidney disease, where low sodium intake is strongly indicated to prevent sodium retention.

Natrium bikarbonat biasanya digunakan dalam masakan sebagai agen penaik. Sebatian tersebut digunakan dalam tepung penaik , di mana kira-kira 30% bikarbonat dicampur dengan pelbagai jenis asid dan diaktifkan dengan air tanpa memerlukan sebarang asid tambahan.
