Aliphatic amines are stronger bases than ammonia (why?) and readily dissolve in acid (why?)
The substitution of an aromatic ring reduces the basicity of an amine (Why?), but it will still generally be soluble in dilute acid
The activity of a radioactive sample is the number of nuclear disintegrations per second, which is equal to the first-order rate constant times the number of radio-active nuclei present.
The most common error students make during a titration is that they add extra NaOH past the endpoint causing the solution to change a dark pink color.
