What else can I help you with?
What substance would you add to NaHCO3(aq) to form a buffer solution?
You would add a weak acid, like acetic acid (CH3COOH), to NaHCO3(aq) to form a buffer solution. The weak acid will react with the bicarbonate ion in NaHCO3 to maintain a stable pH.
What substance would you add to KF in order to form a buffer solution?
To create a buffer solution with potassium fluoride (KF), you would need to add a weak acid, such as acetic acid (CH3COOH), or a weak base, such as ammonia (NH3), to establish both the acidic and basic components necessary for buffering capacity.
If Julie had a 2.5 molar solution of nahco3 and needed to make 50 ml of a 1.0 m solution how much nahco3 and water would she need?
To prepare 50 ml of a 1.0 M NaHCO3 solution from a 2.5 M stock solution, she would need to mix 10 ml of the 2.5 M solution with 40 ml of water. This dilution would result in a final concentration of 1.0 M.
What is the pH of Triethylammonium acetate buffer?
The pH of a buffer solution containing triethylammonium acetate would depend on the concentration of the components. Typically, a buffer solution made from triethylammonium acetate and acetic acid would have a slightly acidic pH, around 4 to 5.5.
What would happen if a small amount of acid were added to a buffered solution?
In a buffered solution, the added acid would likely be neutralized by the buffer system before causing a significant change in pH. The buffer components would absorb the excess H+ ions, helping to maintain the solution's pH relatively stable. If the amount of acid added overwhelms the buffer capacity, the pH of the solution may shift more significantly.

Ch3cooh

What is the balanced equation of HC2H3O2 and NaHCO3?
Above 60 °C, it gradually decomposes into sodium carbonate, water and carbon dioxide. 2NaHCO3 → Na2CO3 + H2O + CO2 Further heating converts the carbonate into the oxide: Na2CO3 → Na2O + CO2

What substance adds or removes Hydrogen ions from a solution?
metals and salts that precipitate it - e.g silver nitrate would remove OH ions from solution. Acids would also tend to remove OH ions from solution
How much 50x TAE buffer will it take to make 3L TAE solution?
To prepare a 3L (3000 mL) TAE solution using 50x TAE buffer, you would need to dilute the 50x buffer by a factor of 50. Therefore, you would take 60 mL of the 50x TAE buffer and add it to 2940 mL of distilled water to achieve a final volume of 3L of 1x TAE solution.
How you classify the solution as a best buffer solution?
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
What would happen if you add a drop of buffer solution at PH 2 into a pool filled with pure PH 7 water?
A drop is insignificant compared to an entire pool, so no change would be observed. However, if the volume of the buffer was comparable to the volume of the pool, pH would change to be somewhere between 2 and 7.
Is there a molar mass of 4.0 PH buffer?
Ph gives the hint about the proton gradient of the solution as pH=-log[H+] we need the inforamtion of the molecular composition of the solution to know about the molar mass.
