Is salt a buffer?
nope....
Is pH7 donor a acid base salt or buffer?
It's a butter.
Aim of buffer preparation?
The purpose of buffers is to maintain a constant pH.
Why is there a need to submerge the agarose gel into a tank of salt solution?
The salt solution serves as a buffer that conducts electricity. Salt is one of the best conductors of electricity.
When preparing a buffer of a given pH an acid should be chosen whose pKa is close to the desired pH?
Yes this is true. This is because for a buffer solution, Ka = [H+] ( [acid] ) / [salt] ) As such by mathematical manipulation, [H+] = Ka ( [salt]/ [acid] ) We must keep in mind that a good buffer must have equal concentrations of acid and salt so as to be able to resist pH change in both directions, by absorbing protons and hydroxide ions. As such the value of ( [salt] / [acid] ) will be 1 and can be cancelled from the equation. [H+] = Ka And, pH = pKa :)
Is salt a buffer?
nope....
What is a z-buffer?
A z-buffer is a buffer for the purpose of tracking the relative depths of different objects in a scene, when creating computer graphics.
Why is HCl and NaCl a good buffer?
No, NaOH is a strong base and NaCl is the salt of a strong acid and a strong base and so has no acidic or basic properties. A buffer solution requires an acidic or basic salt and the corresponding weak acid or base.
Is HBr and NaBr a buffer?
This does not make a buffer because HBr is a STRONG acid, and for a buffer you need a WEAK acid and the salt of the acid.
What is the purpose of a translation lookaside buffer?
The purpose of a translation look aside buffer is to improve virtual address translation speed. There is at least one translation look aside buffer in all laptop, desktop, and server processors.
What is the word for a solution containing either a weak acid and its salt or a weak base and its salt?
A buffer
What is the purpose of the buffer in PCR?
The purpose of the buffer in PCR, I assume you talking about the 5 or 10 times PCR buffer that is provided with enzyme. Buffer is needed to give the correct pH and pottasium ion concentration for the DNA polymerase enzyme (usually DNA polymerase from Thermus aquaticus) to function.
What is the purpose of buffer?
Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.
How do you increase buffer capacity?
Increase the concentration of salt and acid or base. If you are not suppose to increase concentration use more volume of buffer.
Is the purpose of an antacid to buffer or neutralize stomach acid?
Teenmom
Is pH7 donor a acid base salt or buffer?
It's a butter.
Is KClo2 an acid or a base?
It is neither. Potassium Chlorite is a white crystalline substance that is actually a salt.
