The HCl is 0.4876 N. How much water must be added to 100 cc. of the alkali to make it exactly 0.5 N.? !Answer!: 9.0 cc. What is the normal value of a sulphuric acid solution which has a specific gravity of 1.839 and contains 95% H SO by weight? !Answer!: 35.61 N. From the following data calculate the percentage purity of the sample: Wt. sample = 0.9500 gram H SO used = 43.65 cc.
From this weight it is possible to calculate the corresponding weight of HCl in each cubic centimeter of the acid, and in turn the relation of the acid to the normal.
Neither of these elements of uncertainty exists in the case of Tertullian; and therefore, as the text of his New Testament quotations has been edited in a very exact and careful form, I shall illustrate what has been said respecting the corruptions introduced in the second century chiefly from him. Matt. iii. 8. Matt. v. 4, 5. Pst. and Hcl., Memph., Arm., Aeth.
It is desired to dilute a solution of sulphuric acid of which 1 cc. is equivalent to 0.1027 gram of pure sodium carbonate to make it exactly 1.250 normal. 700 cc. of the solution are available. To what volume must it be diluted? !Answer!: 1084 cc. Given the following data: 1 cc. of NaOH = 1.117 cc. HCl.
