Question
Transcribed Image Text:1) An extra strength antacid tablet contains 750 mg of active ingredient, CaCO3. If it takes
22.25 mL of HCI (ag) to neutralize the tablet, how strong is the acid?
2 HCI (аq) + СаCO, (аq) — СаСI,(aq) + HOH () + CO, (g)
2) A beaker containing 25.0 mL of 0.360 M H2SO4 spills on the counter. How much baking
soda, NaHCO3, will be needed to neutralize the acid?
H2SO4 (ag) + 2 NaHCO3 (s) → Na,SO4(aq) + 2 H½CO3 (I)
3) If a 35.75 mL sample of 0.175 M HC1 (aq) solution is neutralized with 0.125 M Mg(OH)2,
how much Mg(OH)2 will be needed?
2 HCI (аq) + Mg(ОH), (аq) — МgCl, (aq) + 2 HОН ()
