Why a mixture of ch3cooh and ch3coona can act as a buffer while a mixture of hcl and nacl can not?
Buffers are made out of what are called weak acids or weak bases. Mixtures of CH3COOH and CH3COONa can act as buffers because they don't break apart completely in solution like HCl and NaCl. As the CH3COOH and CH3COONa are in solution they keep the pH constant by either donating or accepting protons because they don't act like strong acids or bases.
HCl is known as a strong acid where the hydrogen disassociates completely from the chloride.
NaCl is not a buffer because it dissolves completely as welll
What else can I help you with?
Why a mixture of ch3cooh and ch3cooNa can act as a buffer?
Hcl is a strong acid. NaCl is formed by the reaction of Hcl and any base .But NaCl is not a covalent compound and it exists as Na+ and Cl-.Na+and OH- cannot react with EachOther in Aqueous solutions as as the are formed in aqueous solutions and they behave like ions . hence neither H+ nor OH- is consumed by this mixture whereas acetic acid and acetate ions can consume small amt of these ions.Hence the mix. act as buffer
What is the Chemical equation for vinigar and salt for my project?
vinegar's chemical formula is CH3COOH, while salt is NaCl Now Na+ and Cl- are both specator ions. So if the mixture is in water then the equation will go as fallows. CH3COOH + NaCl + H2O ------ NaCH3COO + Cl- + H3O
Compare the degree of ionization of hcl and ch3cooh?
HCL is completely (or nearly 100%) ionized because it is a strong acid whereas the CH3COOH is partially ionized as it is a weak acid.
Which is more highly ionized HCl or CH3COOH?
HCl is more highly ionized than CH3COOH. When HCl dissolves in water, it completely dissociates into H+ and Cl- ions, while CH3COOH only partially dissociates into H+ and CH3COO- ions. This difference is due to the strength of the bonds in the molecules, with HCl having a stronger bond than CH3COOH, making it easier to break apart into ions.
Equal lengths of Mg ribbon are taken in test tubes A and B. HCl is added to test-tube A while CH3COOH is added to test-tube B. In which test tube will the fizzing occur more and why?
Fizzing will occur more in test tube A because: i) HCl is a strong acid while CH3COOH is a weak acid ii) HCl completely dissociates into H+ and Cl- ions while CH3COOH wont completely ionise!!!

Is ch3coona and nach3coo the same thing?
No, ch3coona (sodium acetate) and nach3coo (sodium acetate trihydrate) are not the same thing. Sodium acetate is the anhydrous form, while sodium acetate trihydrate contains three molecules of water.

What is the full name for te buffer?
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
What is the difference between a concentrated buffer and a diluted buffer?
A concentrated buffer has a higher concentration of buffer components compared to a diluted buffer. Concentrated buffers are typically used for preparing stock solutions, while diluted buffers are used for specific applications where a lower concentration is needed. Diluted buffers are often made by diluting a concentrated buffer with water or another solvent.
What are the differences between using mops and MES buffer for a biochemical assay?
Using mops buffer provides a stable pH environment for biochemical assays, while MES buffer is better at maintaining a consistent pH in the presence of oxygen. MES buffer is also less likely to interfere with enzyme activity compared to mops buffer.

How is the buffer and the buffer spring retained inside the extension tube?
The buffer and buffer spring are retained inside the extension tube typically by a retaining plate or a similar mechanism that secures the components in place. The buffer assembly is inserted into the tube, and the retaining plate is then fastened to the rear of the tube, preventing the buffer from moving forward and ensuring the buffer spring remains compressed. This setup allows for smooth operation while maintaining the integrity of the assembly during use.
