First of all please write your chemical symbols with CAPITAL letters.
NB Single letter elements are ALWAYS written as a capital letter. Double letter symbols are always written as , first letter is a capital letter, and the second letter is small/lower case.
So you formula should be written as 'C2H4O2'.
Written in this form it is not known as an acid or a base.
However, I think it is 'CH3C(=O)OH, in which case it is ethanoic (acetic) acid.
Ethanoic acid is a carboxylic acid , and as the name suggest it is an Acid, and carboxylic acids are WEAK acids.
Itis not a base. It is a weak acid.
Sodium hydroxide (strong base) and Sulphuric acid (strong acid)
A salt is formed when a strong acid reacts with a strong base.
It is a strong acid
alkaline obviously! strong acid + strong base= neutral strong acid + weak base= acidic weak acid + strong base= alkaline
Neither, because it a salt of strong base(Calcium) and strong acid(Chloric acid)
it is a non electrolyte C2H5OH is not a base, its an alcohol, ETHYL ALCOHOL so its just an alcohol
Sodium hydroxide (strong base) and Sulphuric acid (strong acid)
A salt is formed when a strong acid reacts with a strong base.
A salt is formed when a strong acid reacts with a strong base.
It is a strong acid
Acetic acid: CH3COOH, or C2H4O2.
alkaline obviously! strong acid + strong base= neutral strong acid + weak base= acidic weak acid + strong base= alkaline
Neither, because it a salt of strong base(Calcium) and strong acid(Chloric acid)
KOH is a strong base.
For countering a strong acid, a strong base like NaOH, LiOH are required.
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
