Sodium Hydroxide Flashcards
Dissolve ______ of Sodium hydroxide in 150 ml of carbon dioxide-free water, cool the solution to room temperature, and filter through hardened filter paper. Transfer 54.5 mL of the clear filtrate to a tight, polyolefin container, and dilute with carbon dioxide-free water to 1000 mL.

54.5 mL
Dissolve 162 g of Sodium hydroxide in 150 ml of carbon dioxide-free water, cool the solution to room temperature, and filter through hardened filter paper. Transfer 54.5 mL of the clear filtrate to a tight, _________, and dilute with carbon dioxide-free water to 1000 mL.
polyolefin container
Sodium hydroxide: accurately weight about ____________, previously crushed lightly and dried at 120 degrees for 2 hours, and dissolve in 75 mL of carbon-free water. Add 2 drops of phenolphthalein TS, and titrate the sodium hydroxide solution to the production of a permanent pink color. Each 204.23 mg of potassium biphthalate is equivalent to 1 mL of 1 N sodium hydroxide
5 g of potassium biphthalate
Sodium hydroxide: Accurately weight about 5 g of potassium biphthalate, previously crushed lightly and dried at _________, and dissolve in 75 mL of carbon-free water. Add 2 drops of phenolphthalein TS, and titrate the sodium hydroxide solution to the production of a permanent pink color. Each 204.23 mg of potassium biphthalate is equivalent to 1 mL of 1 N sodium hydroxide
