Neutralization is a chemical reaction when an acid and a base react with each other in regards of the quantity of each.
Complete Question:
Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCl), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl (aq) + NaHCO3 (aq)--> NaCl (aq) + H2O (I) + CO2 (g).
The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 50.0 mL of a 0.034 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.
Answer:
0.143 g
Explanation:
The balanced reaction of neutralization is:
HCl(aq) + NaHCO3 (aq)--> NaCl(aq) + H2O(I) + CO2(g)
Thus, by the stoichiometry, it is necessary 1 mol of NaHCO3 neutralizes 1 mol of HCl. The number of moles of HCl presented in the stomach is the volume (50.0 mL = 0.05 L) multiplied by the concentration (0.034 M), which is 0.0017 mol.
So, it's necessary 0.0017 mol of baking soda. The molar mass of it is 84 g/mol, so the mass needed is the molar mass multiplied by the number of moles:
m = 84 * 0.0017
m = 0.143 g
Answer:
Did you get the answer to this?
Explanation:
I need this too.
Answer:
The salt that is produces is NaBr.
Explanation:
When an acid react with base it form the salt and water. The reaction is also called neutralization reaction because both neutralize each other.
In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. When pH does not reach to 7 its means there is less amount of one of reactant which is not fully neutralize.
Neutralization reactions are also used as first aid. For example when someone is dealing with HCl for cleaning purpose of toilet and get touched. It is advised to neutralize it with soap, milk or egg white.
Example:
Hydrobromic acid when react with the sodium hydroxide, a salt sodium bromide and water are formed.
Chemical equation:
HBr + NaOH → NaBr + H₂O
Properties of Sodium Bromide:
- It is present in the form of colorless crystals.
- It is also present in powder form.
- It is very toxic.
- It is soluble in water.
- It is bitter in taste and also odorless.
