It serves to make the water a better conductor of electricity.
No, salt is not a buffer. A buffer is a solution that can resist changes in pH when an acid or base is added. Salt is a compound formed by the reaction of an acid with a base, and it does not have the ability to maintain a stable pH.
The purpose of buffers is to maintain a constant 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 :)
The purpose of a buffer in flow injection analysis is to maintain a constant pH and provide the necessary ionic strength for the reaction or detection system. It helps in stabilizing the analyte, improving the precision and accuracy of the analysis, and enhancing the sensitivity of the detection method.
pH7 represents a neutral pH level, indicating a balanced presence of both acidic and basic components. Therefore, pH7 is not specifically classified as a donor, acid, base, salt or buffer in isolation. It depends on the specific context in which it is being used.

A z-buffer is a buffer for the purpose of tracking the relative depths of different objects in a scene, when creating computer graphics.
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.
The hydrolysis of salt can affect the pH of buffer solutions by either increasing or decreasing it. When a salt undergoes hydrolysis, it can release ions that can either react with water to produce acidic or basic solutions, thus impacting the pH of the buffer solution.
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.
A buffer
Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.
Increase the concentration of salt and acid or base. If you are not suppose to increase concentration use more volume of buffer.
To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
The purpose of buffers is to maintain a constant pH.
