Pinterest Is there anything more satisfying than a perfectly seasoned steak cooked to your exact liking? For a meat-lover like me, there is not. Unfortunately it can be hard to get that steakhouse taste at home, unless you know a couple of culinary secrets. Here is my tried and true method for cooking steaks.
Bromate Solutions of bromates acidified with nitric acid 1 in 20yield a white, crystalline precipitate with the addition of 2 or 3 drops of silver nitrate TS, Potato osmosis lab report dissolves by heating.
A pale yellow precipitate is produced with the addition of 1 drop of sodium nitrite TS. Solutions of bromates acidified with nitric acid 1 in 20produce a yellow to reddish brown colour with the addition of 5 or 6 drops of sodium nitrite TS.
With the addition of 1 ml of chloroform and stirring, the chloroform layer becomes a yellow to reddish brown colour. Bromide Free bromine is liberated from solutions of bromides upon the addition of chlorine TS, dropwise.
When shaken with chloroform, the bromine dissolves, colouring the chloroform red to reddish brown. A yellowish white precipitate, which is insoluble in nitric acid and slightly soluble in ammonia TS, is produced when solutions of bromides are treated with silver nitrate TS.
Calcium Insoluble oxalate salts are formed when solutions of calcium salts are treated in the following manner: A white precipitate of calcium oxalate Potato osmosis lab report upon the addition of ammonium oxalate TS.
This precipitate is insoluble in acetic acid but dissolves in hydrochloric acid. Calcium salts moistened with hydrochloric acid impart a transient yellowish red colour to a non-luminous flame. Carbonate Carbonates and bicarbonates effervesce with acids, yielding a colourless gas carbon dioxide which produces a white precipitate immediately when passed into calcium hydroxide TS.
Cold solutions of soluble carbonates are coloured red by phenolphthalein TS, whereas solutions of bicarbonates remain unchanged or are slightly changed.
Chloride Solutions of chlorides yield with silver nitrate TS a white, curdy precipitate which is insoluble in nitric acid but soluble in a slight excess of ammonia TS.
Chlorine, recognizable by its distinctive odour, is evolved when solutions of chloride are warmed with potassium permanganate and dilute sulfuric acid TS. Copper When solutions of cupric compounds are acidified with hydrochloric acid, a red film of metallic copper is deposited upon a bright untarnished surface of metallic iron.
An excess of ammonia TS, added to a solution of a cupric salt, produces first a bluish precipitate and then a deep blue-coloured solution. Solutions of cupric salts yield with potassium ferrocyanide TS a reddish brown precipitate, insoluble in dilute acids.
Ferric salts Potassium ferrocyanide TS produces a dark blue precipitate in acid solutions of ferric salts. With an excess of sodium hydroxide TS, a reddish brown precipitate is formed.
Solutions of ferric salts produce with ammonium thiocyanate TS a deep red colour which is not destroyed by dilute mineral acids. A dark blue precipitate is formed. Ferrous salts Potassium ferricyanide TS produces a dark blue precipitate in solutions of ferrous salts.
This precipitate, which is insoluble in dilute hydrochloric acid, is decomposed by sodium hydroxide TS. Solutions of ferrous salts yield with sodium hydroxide TS a greenish white precipitate, the colour rapidly changing to green and then to brown when shaken.
Iodide Solutions of iodides, upon the addition of chlorine TS, dropwise, liberate iodine which colours the solution yellow to red. Chloroform is coloured violet when shaken with this solution. The iodine thus liberated gives a blue colour with starch TS. Silver nitrate TS produces in solutions of iodides a yellow, curdy precipitate which is insoluble in nitric acid and in ammonia TS.
Iron Solutions of ferrous and ferric compounds yield a black precipitate with ammonium sulfide TS. This precipitate is dissolved by cold dilute hydrochloric acid TS with evolution of hydrogen sulfide. Magnesium Solutions of magnesium salts in the presence of ammonium chloride yield no precipitate with ammonium carbonate TS, but a white, crystalline precipitate, which is insoluble in ammonia TS, is formed upon the subsequent addition of sodium phosphate TS.
Manganese Solutions of manganese salts yield with ammonium sulfide TS a salmon-coloured precipitate which dissolves in acetic acid.
Nitrate When a solution of a nitrate is mixed with an equal volume of sulfuric acid, the mixture cooled, and a solution of ferrous sulfate superimposed, a brown colour is produced at the junction of the two liquids.Determining the Water Potential of Potato Tuber Cells Essay - Determining the Water Potential of Potato Tuber Cells I will carry out an investigation that will enable me to determine the water potential of the tested potato tuber cells.
