Is a sodium fatty acid salt the same as a carboxylic acid salt?
A fatty acid salt is a kind of carboxylic acid salt. But not all carboxylic acid salts are fatty acid salts.
What are requirements for a buffer solution?
Requirements for a Buffer Solution:There are three requirements for buffer:• Must be a mixture of weak acid and its salt or weak base and its salt• A buffer must contain relatively large concentration of acid to react with added base (OH-) and also must contain similar concentration of base to reaction with added acid (H+).• The acid and base components of the buffer must not consume each other in a neutralization reaction.
Can an acid and a base react to form an acid?
NO!!!! Remember the general acid reaction equations. Acid + Base = Salt +Water Acid +Alkali = Salt + Water Acid +Metal = Salt + Hydrogen Acid + Carbonate = Salt + Water + Carbon Dioxide. NB An Alkali is a soluble Base.
What you get when acid meets metal?
Remember the general acid reactions. Acid + metal = salt + hydrogen Acid + Alkali = Salt + Water Acid + Base = Salt + water Acid + Carbonate = Salt +Water + Carbon dioxide. NB An Alkali is a soluble Base.
What is the general word equation for salt formation by neutralization?
There several general equations:- they are: - Acid + Alkali = Salt + Water Acid + Base = Salt + Water Acid + Metal = Salt + Hydrogen Acid + Carbonate = Salt + Water + Carbon Dioxide.
Experiment in acid base and salt?
An example; preparation of sodium chloride in laboratory: NaOH + HCl = NaCl + H2O
If sodium nitrate was formed what acid was used?
During the formation of a salt anion comes from acid so in this case acid used must be Nitric acid.
Is a sodium fatty acid salt the same as a carboxylic acid salt?
A fatty acid salt is a kind of carboxylic acid salt. But not all carboxylic acid salts are fatty acid salts.
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 :)

Explain why must washed the lead iodide precipitate with alcohol in lead iodide salt preparation?
to remove part of water in the precipitate
Is salt alkali or acid?
salt is an acid
What acid is in salt?
Salt doesn't contain any acid.
What is formed when an acid and a base is mixed?
when an acid and a base combine, salt and water are formed. This process of reaction of an acid and base is called neutralisation.
Can an acid and a base react to form an acid?
NO!!!! Remember the general acid reaction equations. Acid + Base = Salt +Water Acid +Alkali = Salt + Water Acid +Metal = Salt + Hydrogen Acid + Carbonate = Salt + Water + Carbon Dioxide. NB An Alkali is a soluble Base.
What kind of acid is NaCl?
It is not an acid. It is a salt. It is actually the salt we call salt (sodium chloride).
Is nah2po4 an acid salt or basic salt or normal salt?
Sodium hydrogen phosphate is an acid.
