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
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 PH when buffer is added to water?
Since we do not know the buffer or its concentration, we cannot provide an answer.
Is HF and KF a buffer?
No, HF and KF do not form a buffer solution because a buffer contains a weak acid and its conjugate base (or a weak base and its conjugate acid). HF and KF are both strong acids, so they cannot act as a buffer system.
Which one of the following combinations cannot function as a buffer solution: a) HCl and NaCl, b) NH and NHCl, or c) HNO and NaNO?
The combination that cannot function as a buffer solution is a) HCl and NaCl.
What is the chemical formula for pickle juice?
Pickle "juice" is typically water and vinegar, plus other ingredients added for flavour - chillis for example. Usually white (spirit) vinegar is used.
How can a baked cake mixture be separated?
The mixture cannot be separated after it is baked.
Represents a way a mixture cannot be separated?
One way a mixture cannot be separated is if its components are chemically bonded together, forming a compound. This results in a homogeneous mixture where the individual components cannot be physically separated.
Is NaF and NaOH a buffer?
No, NaF and NaOH do not form a buffer solution together as a buffer solution requires a weak acid and its conjugate base, or a weak base and its conjugate acid. NaF is the salt of a weak acid (hydrofluoric acid) and a strong base (NaOH), so it does not act as a buffer. NaOH is a strong base and cannot act as a buffer solution by itself.
What is the balanced equation for the reaction of phosphoric acid and acetic acid?
There is no reaction. Two acids cannot react with each other.
Any mixture in which different parts cannot be seen?
A homogeneous mixture, also known as a solution, is one in which the components are evenly distributed and the different parts cannot be visually distinguished. This type of mixture appears uniform throughout and has consistent properties.
Is lotion a mixture or a compound?
it is a mixture, specifically homogenous because you cannot identify the particles of it......
