Al (Monteinartini, Jazz. eh. it. 22. 397); very si. sol. in most jrganic acids, but solubility is increased by presence of NaCl. Very easily sol. in cone, or dil. KOH, or NaOH + Aq. Slowly attacked by NH4OH + Aq (Wiihlcr) ; sol. in BaO.^Ha + Aq (Beckmann, J. pr. (2) 26. 385) ; slowly sol. in CaO.^Ha + Aq. SI. attacked by sulphates, or nitrates+ Aq, but all chlorides, bromides, and iodides, except those of the alkalies and alkaline earths, even AICI3 +An, dissolve the metal. Insol. in alum, orinNaCl + Aq, but sol. in alum + NaCl+ Aq (Tissier, C. R. 41. 362); .sol. in NaCl + Aq (Deville, A. ch. (3) 43. 14) ; sol. in neutral FeCla + Aq in vacuo. (Weeren, I.e.) Violently attacked byCuClo +Aq. (Tommasi, Bull. Soc. (2) 37. 443.) Attacked by POCl., at 100°. (Renitzer, B. IS. 845.) Not attacked by sugar+ Aq. (Klein, C. R. 102. 1170.) Less easily attacked than ordinary metals (iron, copper, lead, zinc, tin) by air, H2O, wine, beer, coli'ee, milk, oil, butter, fats, etc. Vinegar dissolves 0349 g. from a sq. decimetre in 4 months, and 5 % NaCl + Aq, only 0045 g. in the same time. (Ballaud, C. R. 114. 1536.) The action of various substances contained in foods and drinks on compact Al as it occurs in utensils is very slight. Hard or soft water, whether cold or hot, showed no action in 8 days ; 1 % solutions of tartaric, tannic, and acetic acids had no action in same time, also 5 % boric, carbolic, and salicylic acids. 4 % and 10 % acetic acid dissolved only 0*4 mg. of Al, while 10 % acetic acid dissolved 2'1 mg. from a roughened piece of Al foil in 8 days. 1 % soda solution dissolved 15 mg. in 8 days. (Rupp, Dingl. 283. 119.) Similar results Avere obtained by Arche. (Dingl. 284. 255.) Liquids which are ordinarily contained in foods and drinks do not attack sheet Al except in a very small degree. The following losses in weight in mg. by the action of the given liquids on 100 sq. centimetres sheet alumi- num for 6 days were obtained : Liquids. Loss in mg.
