Another reagent that could be used in place of HCL to precipitate cations of the silver group?
HNO3 which forms white precipitate..
What compound containing potassium reacts with barium nitrate to form a white precipitate?
Potassium sulphate - K2SO4; the precipitate is BaSO4 - the reaction is frequently used in gravimetric analysis.
What two forms of punctuation can be used to create compound sentences?
Two forms of punctuation that can be used to create compound sentences are commas (,) and semicolons (;).
How are mass calculations used?
Mass percentage calculations determine the percentage of an element based on mass in a compound. This can then be used to determine the percentage in a compound of each individual element.
What is an organic compound called that is used to store energy and forms important parts of biologic membranes?
A lipid organic compound is used to store energy and forms important parts of biological membranes.lipids
What are the principle of Esbach reagent?
Esbach reagent is used to detect albumin in urine. The picric and citric acids forms a precipitate with albumin.
What test is commonly used to determine if a compound is ionic or covalent?
electricity
What is Zeisel's method?
Zeisel's method is used to estimate the alkoxy linkages in an organic compound. In this method the organic compound containing alkoxy group is treated with hydrogen iodide and the alkyl halide formed is further treated with silver nitrate to precipitate silver iodide In this reaction only hydrogen iodide can be used because it consists of an ionic bond, while HF, HCl, HBr contain covalent bond where an iodide ion is liberated which forms a precipitate with silver nitrate. The silver iodide can be weighed and from its weight the number or alkoxy group can be estimated.
What does Tollens reagent Fehlings solution 2 4-Dinitrophenylhydrazine and Benedicts solution test for and what are the results?
Brady's reagent (2,4-DNP) forms a orange precipitate for all carbonyl compounds (C=O functional group), both aldehydes (primary) and ketones (secondary). However, recrystalisation of the orange precipitate gives characteristic melting points of the crystal for each carbonyl compound (therefore the presence of an orange precipitate indicates a carbonyl compound and the melting point of the crystallised precipitate indicates the type of carbonyl compound; aldehyde or ketone). Tollen's reagent (diamminesilver nitrate solution) is reduced and forms a silver mirror when heated with an aldehyde. It distinguishes between aldehydes and ketones as ketones do not react (no silver mirror formed) as they can not be oxidised further. Fehling's solution (copper II ions in sodium hydroxide) is reduced from a blue solution (Cu II ions) to a brick red precipitate (Cu I ions) when heated in the presence of an aldehyde. Ketones do not react as they can not be oxidised further. The Benedict's test is used in organic chemistry to distinguish between reducing sugars (brick red precipitate formed) and non-reducing sugars (no reaction).
