Why would you use sodium hydrogen carbonate and potassium hydroxide in a photosynthesis experiment?
They aare used in order to absorb carbon dioxide.
Would you need to use sodium carbonate for the diazotization of m-nitroaniline?
You need to use sodium carbonate when you are attempting to diazotize a poorly soluble acid, such as sulfanilic acid. m-nitroaniline isn't acidic, so adding sodium carbonate would have no effect.
How would you write aluminum hydrogen carbonate?
Al(HCO3)3
In a double displacement reaction between calcium nitrate and sodium carbonate the precipitate produced would be?
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
What would adding sodium hydride to ethanol produce?
you will get Sodium ethoxide and hydrogen gas
What will happen if a solution of sodium hydrogen carbonate heated?
Sodium carbonate would be deposited at the bottom of the solution.
What is formula of 'Sodium II Hydrogen Carbonate'?
It would have to be Na(HCO3)2 But no such thing exists.This would require sodium to form a 2+ ion.It can only form a 1+ ion.The real formula for sodium hydrogen carbonate is NaHCO3 .This would be sodium I hydrogen carbonate, though the roman numeral is not needed in this case.
What happens when 2 ml of HCL is added to sodium carbonate?
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
What substance would you add to NaHCO3(aq) to form a buffer solution?
Sodium carbonate and and sodium hydrogen carbonate form a buffer solution.
What is the dissolution of sodium hydrogen carbonate?
I guess it would be NaOH and CO2. This explains why it is an alkaline buffer
Why sodium carbonate solution is alkaline in nature?
Sodium carbonate solution is alkaline because of the carbonate ion. Sodium ions do not change the pH. However, carbonate, being the conjugate base of a weak acid (carbonic acid/hydrogen carbonate) does affect the pH. The carbonate ions can abstract a proton to form hydrogen carbonate, HCO3-. When the proton is abstracted from water, hydroxide ions form which results in a higher pH (more basic).
Would would you use to cancel out sulfuric acid?
Sodium bicarbonate (or sodium hydrogen carbonate/baking soda) is commonly used to neutralize sulfuric acid, such as during a spill.
What is NAHCO3 in H2O?
Na is sodium which has a charge of +1. This is your cation HCO3 is Hydrogen Carbonate which has a charge or -1. This is your anion. Thus your final answer would be Sodium Bicarbonate
Why would you use sodium hydrogen carbonate and potassium hydroxide in a photosynthesis experiment?
They aare used in order to absorb carbon dioxide.
Need Help with my pH calculation?
1) 0.10 mol of solid sodium hydrogen carbonate and 0.20 mol of solid sodium carbonate are dissolved in the same beaker of water, transferred to a volumetric flask and made to 250.0 mL. The Ka for HCO3 - is 4.7 x 10-11. a) What is the pH of the resulting buffer? b) What is the pH of solution after 20.00 mL of 0.050 mol L-1 hydrochloric acid solution is added to 25.00 mL of the original solution? c)What is the pH of the resulting buffer after 0.040 g of solid sodium hydroxide is added to 25.00 mL of the original solution? 2) Plan how you would make 100.0 mL of a buffer solution with a pH of 10.80 to be made using only sodium carbonate, sodium hydrogen carbonate and water.Youshould specify the amounts of sodium carbonate and sodium hydrogen carbonate that you would use. ( the ration acid to base is 3:1)
What does Sodium hydrogen carbonate plus nitric acid equals?
Calcium hydroxide and nitric acid yield calcium nitrate and water. Ca(OH)2 + 2HNO3 --> Ca(NO3)2 + 2H2O
What would you observe if you mixed sodium carbonate and water?
If you mix sodium carbonate and water, you would observe that the sodium carbonate dissolves in the water. This is because sodium carbonate is highly soluble in water. The solution may also become slightly warm due to the dissolution process.
