When they mix they react to form a salt, and gas is released as a by-product.

What are Alka-Seltzer tablets made out of?
Alka-Seltzers are a combination of sodium bicarbonate, aspirin, and anhydrous citric acid.
Why does seltzer fizz?
If you look at the ingredients for Alka-Seltzer, you will find that it contains citric acid and sodium bicarbonate(baking soda). When you drop the tablet in water, the acid and the baking soda react -- this produces the fizz.
What is the reaction of alkazelter when you put in the water?
Alka-Seltzer contains citric acid and sodium bicarbonate (baking soda). When the tablet is dropped in the water, the acid and base react producing fizz.
Why does indigestion medicine contains Citric Acid?
Citric acid is a mild acid, and sodium bicarbonate is a mild base. When you combine the two in H2O, the acid reacts with the bicarbonate releasing carbon dioxide gas (and I think forming sodium citrate) and neutralizes the solution. This gas is the "fizz-fizz" that follows the "plop-plop" in the Alka-Seltzer ad, and it is the reason why it is called Alka- SELTZER. I'm not a chemist, but I suspect the sodium citrate is a harmless byproduct rather than a useful medicine. Sodium citrate is mostly used as a chelate or antioxydant in prepared foods and medications. By the way, the active ingredient in this formulation is 325 mg aspirin. I'm not sure how aspirin helps indigestion since it irritates a lot of people's stomachs. But I think the idea behind the acid/base reaction is to have some of that fizz enter the stomach where it will become trapped eventually causing you to belch.
Is alka seltzer neutral?
Alka seltzer is technically both. It is a dry mixture of sodium bicarbonate (a base) and citric acid (an acid). When mixed with water, the acid and base react with each other and produce carbon dioxide (the fizz), and sodium citrate.
What is the difference between citric acid and carbonating?
Citric acid gives a lemon or orange flavor . Carbonating adds fizz to a liquid.
What happens when alka seltzer is placed in water?
If you look at the ingredients for Alka-Seltzer, you will find that it contains citric acid and sodium bicarbonate(baking soda). When you drop the tablet in water, the acid and the baking soda react -- this produces the fizz.
An indegestion powder contains sodium hydrogencarbonate and a small amount of citric acid. the powder starts to fizz when it is added to water. what gas is given off when the mixture fizzes?
carbon dioxide
What does citric acid and bicarbonate soda do to fizz?
Gives it a tangy taste.More Details: Citric acid is a weak organic acid. It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. Inbiochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of virtually all living things. It can also be used as an environmentally benign cleaning agent.Citric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices[3]). The concentrations of citric acid in citrus fruits range from 0.005 mol/L for oranges and grapefruits to 0.30 mol/L in lemons and limes. Within species these values vary depending on the cultivar and the circumstances in which the fruit was grown.For More Check My Profile- theScienceIsAwsome
What is in ENO to make it fizz?
ENO powders, and other medical effervescents, are made to fizz through a combination of an acid and a water-soluble alkali that contains carbonate or bicarbonate, in addition to the active ingredient used for the medical curation. The reaction between the acid and the alkali has Carbon Dioxide as a by-product, which causes the 'fizz' effect. In the case of ENO, it is: H3C6H5O7 (aq) + 3NaHCO3 (s) → 3 CO2 + 3 H2O(l) + Na3C6H5O7 (aq) The 'HCO3' in the second reactant (left of arrow) represents the Bicarbonate in this reaction. The first reactant is the acid, known as citric acid, found naturally in citrus fruits. It can also be written C6H8O7
How do you neutralize 99 percent dichloroacetic acid with sodium bicarbonate such that resulting solution provides sodium dichloroacetate salt in known concentration or 250mg in each ml?
if you are an amateur chemist and don't have ph meter and other equipment ..then simply add sodium bicarbonate to the DCA until the fizz or the bubbling of co2 stops and the bicarbonate dissolves without effervescence thats it ! you have successfully neutralized and buffered the DCA ..dilute suitably with water to get the desired concentration
Is water in soda?
Soda pop, many people's favorite beverage, is made up of mostly water with a little carbon dioxide and a little sweetener and flavoring.Baking Soda or Sodium Bicarbonate (NaHCO3) is a weak base that technically does not contain water (H2O). However, its conjugate acid, Carbonic Acid (H2CO3) is a unique molecule that that will dissociate into Water (H2O) and Carbon Dioxide (CO2).Carbonic Acid is responsible for both the fizz as well as the acidity of soda pop.The conversion from Sodium Bicarbonate into Carbonic Acid, then dissociating into Water and Carbon Dioxide is also responsible for the fizz in Alka-Seltzer.
