Is lemon lime soda healthier than other types of soda?
Sierra Mist is the healthiest soda. A single can of Sierra Mist Lemon-lime soda contains 140 calories, 37 g of carbs, and 35 mg of sodium, which allows it to place slightly better than its closest competitor. Of course, you should still take care not to drink too much despite that. 2. Sprite.
What is soda lime, and what is its mixture?
Soda lime, solid is generally a white to grayish white colored solid. It is the mixture of calcium hydroxide and sodium orpotassium hydroxide, both corrosive materials. It is noncombustible and soluble in water with release of heat.
Is NaOH soda lime?
Soda lime is a mixture of NaOH & CaO chemicals, used in granular form in closed breathing environments, such as general anaesthesia, submarines, rebreathers and recompression chambers, to remove carbon dioxide from breathing gases to prevent CO2 retention and carbon dioxide poisoning.
Is CaCO3 soda lime?
Lime Softening Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause non-carbonate hardness. When lime and soda ash are added, hardness-causing minerals form nearly insoluble precipitates. Calcium hardness is precipitated as calcium carbonate (CaCO3).
What is soda lime called?
Soda-lime is the common name for Sodium calcium hydrate (CaHNaO2. ).
How is soda lime formed?
Silica is added to the granules to provide hardness and minimize alkaline dust formation. Neutralization of carbon dioxide with soda lime begins with reaction of carbon dioxide with water present in the soda lime granules and the subsequent formation of carbonic acid.
What is CaCO3 called?
Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen, and calcium.
What is CaCO3 used for?
Personal Health and Food Production: Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It also is found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine.
What is Gypsum formula?
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4·2H2O.
What is the formula of baking soda?
NaHCO₃Sodium bicarbonate / Formula3. Baking Soda. Baking soda is a white crystalline compound with a slightly salty taste. Its chemical formula is NaHCO3 and is generally known as sodium bicarbonate.
What is the formula of quicklime?
CaOCalcium oxide / FormulaThe chemical formula of lime or quicklime is CaO. The chemical name of lime is calcium oxide. On the other hand, the chemical formula of limewater is Ca(OH)2 and the chemical name of this substance is calcium hydroxide.
What is the chemical formula of plaster of Paris?
Plaster of Paris is also referred to as Gypsum plaster. The chemical formula of Plaster of Paris is written as CaSO4·1/2H2O.

3. What is Ca(OH)2?
Calcium hydroxide, usually alluded to as slaked lime, is portrayed by the compound recipe Ca(OH)2. It is an inorganic compound that has a white, fi...
4. Can we eat soda lime?
No, we cannot eat soda lime. Soda-lime is a highly corrosive and strongly alkaline salt. It can affect the gastrointestinal tract when engulfed and...
5. Why does soda-lime have higher reactivity than calcium hydroxide alone?
Soda-lime has sodium hydroxide(NaOH) along with calcium oxide (CaO) as a constituent. NaOH is a strong base hence it leads to the higher reactivity...
6. Which type of compound soda lime is it?

Anaesthetic use
During the administration of general anaesthesia, the gases expired by a patient, which contain carbon dioxide, are passed through an anaesthetic machine breathing circuit filled with soda lime granules. Medical-grade soda lime includes an indicating dye that changes color when the soda lime reaches its carbon dioxide absorbing capacity.
Rebreather use
Exhaled gas must be passed through a carbon dioxide scrubber where the carbon dioxide is absorbed before the gas is made available to be breathed again. In rebreathers the scrubber is a part of the breathing loop. Color indicating dye was removed from US Navy fleet use in 1996 when it was suspected of releasing chemicals into the circuit.
Analogy with the alkali-silica reaction
A similar reaction to above, also catalysed by sodium hydroxide, is the alkali-silica reaction, a slow degradation process causing the swelling and the cracking of concrete containing aggregates rich in reactive amorphous silica. In a very similar way, NaOH greatly facilitates the dissolution of the amorphous silica.

Overview
Chemical reaction
The overall reaction is:
CO2 + CaO→ CaCO3 + heat (in the presence of water)
Each mole of CO2 (44 g) reacting with calcium hydroxide produces one mole of water (18 g).
The reaction can be considered as a strong-base-catalysed, water-facilitated reaction.
The reaction mechanism of carbon dioxide with soda lime can be decomposed in three element…
