No test.. You can order standard from Sigma and compare ur sample with FT-IR... Thats all.
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
To determine the limiting reagent using the heights of precipitate, you can first measure the height of the precipitate formed in a reaction. By comparing the heights of precipitate from different trials with varying amounts of reactants, you can identify which reactant runs out first. The limiting reagent will correspond to the trial with the least height of precipitate, indicating that it was consumed completely before the other reactants. This method allows for a visual and quantitative assessment of the limiting reagent based on precipitate formation.

Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
The Benedict's reagent is commonly used to detect the presence of glucose in a solution. This reagent changes color from blue to green, yellow, orange, or red, depending on the amount of glucose present.
tilt & gently shake the bottle until the desired amount of solid is dispensed.
Use a graduated pipette or syringe to measure and transfer 5ml of liquid reagent from the large reagent bottle. Make sure to carefully handle and dispense the reagent to avoid spills and contamination.

A Lucas test is a biochemical test used primarily to identify the presence of certain types of carbohydrates, specifically reducing sugars such as glucose and fructose. It involves the use of a reagent called Lucas reagent, which contains zinc chloride in hydrochloric acid. When a carbohydrate is mixed with the reagent, a reaction occurs that produces a precipitate or a color change, indicating the presence of reducing sugars. This test is particularly useful in the analysis of sugars in various food and fermentation processes.
