indicators for acid

. Acid base indicator methyl orange is obtained by coupling of diazonium salt of sulphanilic acid and N, N - dimethylamilin..

Since carboxylic acids are amongst the earliest organic compounds to be isolated from nature, a large number of them are known by their common names. The common names end with the suffix-ic acid and have been derived from Latin or Greek names of their natural sources. For ..

. The IUPAC names are derived by replacing the ending -oic acid with -amide or carboxylic acid with carboxamide. The position of the substituent at the nitrogen atom, if any, is indicated by the letter ..

These reactions confirm the presence of a carbonyl group in glucose. 3. Glucose reduces ammoniacal silver nitrate solution (Tollens reagent) to metallic silver and also Fehlings solution to reddish brown cuprous oxide and itself gets oxidized to gluconic acid. This confirms the presence o..

We have seen that concept of ionic product of water enables us to classify solutions as acidic, basic or neutral by specifying H 3 O + ion concentration. The pH scale was devised by P.L Sorensen (1909) is defined as negative logarithm of hydronium ion concentration in moles per litre. ..

Auxins are phytohormones that are mainly concerned with cell enlargement. They affect the plasticity of the cell walls and induce them to grow. The name 'auxin' was derived from the Greek word 'auxein' meaning to increase. They were discovered through a series of experiments. Darwin and his son'..

The physical states of the reactants and products are specified. We use 's' for solids, 'l' for liquids and 'g' for gases. Sometimes 'aq' is used for aqueous - to represent that the given substance has been dissolved in excess of water. The strength of acid or base used in the rea..

Naming Compounds With More Than One Different Functional Groups - When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent chain is done so that the functional group ..

The organic compound is fused with sodium peroxide. The fused mass is then extracted with water. The aqueous solution so obtained is boiled with concentrated nitric acid, and ammonium molybdate solution is added to it. A yellow solution or precipitate indicates the presence of..

. But if T 2 phage with radioactive DNA was used, the heavier bacterial pellets were radioactive. This experiment indicated that during infection with the virus, it is the DNA that actually entered the bacteria. This finding suggests that it is the viral DNA and not protein that contains ..
