1) FALSE - Proton and hydrogen ion are not the same thing. Proton is a positively charged particle, whereas a hydrogen ion is an atom of hydrogen that has lost its electron, leaving only a proton and no electrons.
2) FALSE - Hydroxide ions are actually found in basic solutions, not acidic solutions. In acidic solutions, there are more hydrogen ions than hydroxide ions.
3) TRUE - A buffer consists of a weak acid and its conjugate base, not a strong acid and its conjugate base.
