What reading level is A Laboratory Manual of General Chemistry book?
To quickly assess the difficulty of the text, read a short excerpt:
To prove LABORATORY MANUAL OF GENERAL CHEMISTRY 53 the reaction, Na 2 CO 3 +Ca(OH) 2 =CaCO 3 +2NaOH, proceed as follows: Wash the insoluble residue in the dish twice by filling nearly full of water, stirring, letting the substance settle and pouring off the water. Now put a little water on the insoluble substance in dish, and place about the same amounts of lime and water in another dish and pour upon each about 10 c. C. Of dilute HC1. Compare the amounts of carbon dioxide given off. Now treat ...the 5 c. C. Reserved solution of sodium car- bonate and the same volume of the filtrate with the same volumes of HC1 and compare the gas given off. You started with a soluble car- bonate and a very sparingly soluble hydroxide, "slaked lime. " What did you obtain by the reaction?
110. Comparative Tests of Crude and Pure Sodium Hydroxides: Dissolve 1-2 grams of crude and pure NaOH, each in 10 c. C. Of distilled water. Make each acid throughout with dilute nitric acid and warm. If either gives off gas test for carbon dioxide as in 90.
