Unformatted text preview: solution PRE-LAB QUESTIONS: 1. a.) Use caution with HCl solution because Hydrochloric Acid can be toxic, corrosive and an irritant to your skin. b.) To prepare for discarding, add .5 mL of 6M NaOH to your beaker, checking the pH. 2. a.) A strong acid is an acid that completely dissociates in water, forming a weak conjugate base and a Hydronium ion, while a strong base is a base that completely dissociates in water, forming a weak conjugate acid an Hydroxide ion. b.) A strong acid is an acid that completely dissociates in water, forming a Hydronium ion and a weak conjugate base, while a weak acid is an acid that only dissociates into 10% or less of Hydronium ion. 3. a.) pH= -log(1.5E-3)= 2.82 b.) pH= 14-(-log(3.1E-4))= 10.5 c.) [H+]= 10^(-8.42)= 3.80E-9 d.) [H+]= 10^(-(14-5.58))= 3.80E-9...
