Nitrate de barium

The names adopted for salts consisted of a generic part derived from the acid and a specific part from the metallic base r oxide de plomb + I acide sulfurique le sulfate de plomb. The names for salts of acids containing an element in different degrees of oxidation were given different terminations sufte de soude and sulfate de soude for sodium sulfite and sulfate, and nitrite de baryte and nitrate de baryte for barium nitrite and nitrate.

Pipette 25 mL barium ion solution (ca 0.01 M) into a 250 mL conical flask and dilute to about 100 mL with de-ionised water. Adjust the pH of the solution to 12 by the addition of 3-6 mL of 1M sodium hydroxide solution the pH must be checked with a pH meter as it must lie between 11.5 and 12.7. Add 50 mg of methyl thymol blue/potassium nitrate mixture [see Section 10.50(C)] and titrate with standard (0.01 M) EDTA solution until the colour changes from blue to grey. 

Polarography has also been applied to the determination of potassium in seawater [535]. The sample (1 ml) is heated to 70 °C and treated with 0.1 M sodium tetraphenylborate (1 ml). The precipitated potassium tetraphenylborate is filtered off, washed with 1% acetic acid, and dissolved in 5 ml acetone. This solution is treated with 3 ml 0.1 M thallium nitrate and 1.25 ml 2M sodium hydroxide, and the precipitate of thallium tetraphenylborate is filtered off. The filtrate is made up to 25 ml, and after de-aeration with nitrogen, unconsumed thallium is determined polarographically. There is no interference from 60 mg sodium, 0.2 mg calcium or magnesium, 20 pg barium, or 2.5 pg strontium. Standard eviations at concentrations of 375, 750, and 1125 pg potassium per ml were 26.4, 26.9, and 30.5, respectively. Results agreed with those obtained by flame photometry. 

I prepared a quantity of muriate suroxygeni de baryte (barium chlorate), and treated a dil, soln. of this salt with dil. sulphuric acid, taking care to add no more acid than is needed to sat. the baryte.. .. In this way, I prepared a soln. of the acid quite free from sulphuric acid and from baryta. The soln. gave no precipitate with silver nitrate it contained Vacide chlorique in aq. soln. 

Ammonium perchlorate, NH4C104.—The perchlorate is formed by mixing solutions of barium perchlorate and ammonium sulphate, by the action of ammonium nitrate on sodium perchlorate,8 and by that of ammonium chloride on calcium or magnesium perchlorate.10 It forms rhombic,11 doubly refracting crystals,12 of density 1 88 at 25° C. Its solubility at 18° C. is 21 07 grams in 100 grams of water.18 It is de-...
