Sodium Bicarbonate

Question 1

Sodium bicarbonate: Weight accurately about ____ of Sodium Bicarbonate, mix with 100 mL of water, add methyl red TS, and titrate with 1N hydrochloric acid VS. Add the acid slowly, with constant stirring, until the solution becomes a faintly pink color. Heat the solution to boiling, cool, and continue the titration until the faint pink color no longer fades after boiling. Each mL of 1 N hydrochloric acid is equivalent to 84.01 mg of NaHCO3

Answer 1

3 g

Question 2

Sodium bicarbonate: Weight accurately about 3 g of Sodium Bicarbonate, mix with 100 mL of water, add _______, and titrate with 1N hydrochloric acid VS. Add the acid slowly, with constant stirring, until the solution becomes a faintly pink color. Heat the solution to boiling, cool, and continue the titration until the faint pink color no longer fades after boiling. Each mL of 1 N hydrochloric acid is equivalent to 84.01 mg of NaHCO3

Answer 2

methyl red TS

Question 3

Sodium bicarbonate: Weight accurately about 3 g of Sodium Bicarbonate, mix with 100 mL of water, add methyl red TS, and titrate with ______.

Answer 3

1N hydrochloric acid VS

Question 4
