ACID AND BASE TITRATION

DESCRICE HOW YOU WOULD FILL A PIPETTE (8PTS)

RINSE WITH DEIONIZED WATER , RINSE WITH SOLUTION ITS GOING TO CONTAIN , FILL TO MARK , READ FROM BOTTOM OF MENISCUS ON GRADUATION MARK , EYE LEVEL , DRAIN WITH GRAVITY , DONT FORCE OUT LAST DROP , TIP AGAINST FLASK

DESCRIBE HOW YOU WOULD FILL A BURETTE (8PTS)

RINSE WITH DEIONISED WATER , RINSE WITH SOLUTION ITS GOING TO CONTAIN , FILL AND OPEN TAP TO LET IT HIT 0 , FILL WITH A FUNNEL , LAST BIT DROP WISE , BOTTOM OF MENISCUS ON GRAD MARK , EYE LEVEL , RETORT STARD VERTICAL AND STEADY
