1
Q
pH indicator definition
A
weak acids in a solution where the weak acid has a different colour to the conjugate base
2
Q
equivalence point
A
the volume of a solution that completely reacts the volume of another solution
3
Q
end point
A
the point in a titration where there are equal concentrations of the weak acid and conjugate base forms of the indicator
4
Q
butanoic acid + sodium
A
sodium butanoate + water
5
Q
hydrogen bonding of carboxylic acids
A
form hydrogen bonds with water, ammonia, and each other carboxylic acid molecules
6
Q
solubility of carboxylic acids
A
- dissolve best in polar solvents (especially solvents that form hydrogen bonds with the carboxylic acid groups)
- as number of carbon atoms in the molecule increases, the solubility in polar solvents decreases, and the solubility in non-polar solvents increases
