CAN NaOH(aq)+Co2 yield NaHCO3
PLEASE ANSWER DEEPLY!!!!!!!!!!!!!!!
wikipedia has a nice article on sodium bicarbonate. In it, we find:
NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide. The initial reaction produces sodium carbonate:
CO2 + 2 NaOH → Na2CO3 + H2O
Further addition of carbon dioxide produces sodium bicarbonate, which at sufficiently high concentration will precipitate out of solution:
Na2CO3 + CO2 + H2O → 2 NaHCO3
So, the answer is yes, and a little web search could have saved you the trouble of posting here (and me the trouble of doing your homework).
A word of caution. I ALMOST answered this NO, because I read your Co2 as a cobalt compound.
CO is carbon monoxide
Co is cobalt
co is the abbreviation for company.
Be careful with your caps key. Use it appropriately.
Yes, NaOH(aq) can react with CO2 gas to yield NaHCO3. The reaction is as follows:
2 NaOH(aq) + CO2(g) -> Na2CO3(aq) + H2O(l)
To understand how this reaction occurs, we need to look at the properties of the compounds involved.
NaOH is sodium hydroxide, a strong base, and CO2 is carbon dioxide, a gas. When NaOH dissolves in water (aq), it dissociates into Na+ ions and OH- ions. Similarly, CO2 gas, when dissolved in water, forms carbonic acid (H2CO3) due to its reaction with water.
Now, in the reaction, the OH- ions from NaOH react with the H+ ions from the carbonic acid (H2CO3) to form water (H2O). This forms the H2O(l) on the product side.
The remaining ions, Na+ and HCO3- (bicarbonate ion), combine to form sodium bicarbonate or NaHCO3(aq). This is because the Na+ ion has a positive charge, while the HCO3- ion has a negative charge, resulting in an ionic bond between them.
To carry out this reaction, you would need to mix a solution of NaOH(aq) with a source of CO2 gas, such as passing it through the solution or bubbling the gas through the solution. The reaction will occur, resulting in the formation of NaHCO3(aq) and water (H2O).
It's important to note that the reaction can also proceed further to form Na2CO3(aq) (sodium carbonate) and water, if excess CO2 is present. This is because the bicarbonate ion (HCO3-) can react with another CO2 molecule to form the carbonate ion (CO32-).
