How do you separate sand, sodium chloride, and ammonium chloride? Are sodium carbonate and sodium bicarbonate the same? Does sodium bicarbonate dissolve in water? Describe how to prepare a sodium bicarbonate-carbonate buffer solution with a pH of 10. ...
In a 100mL three-necked flask, add 7.0mL N,N-dimethylformamide, cool to 0~5℃, slowly add 1.0mL phosphorus oxychloride dropwise, complete the dripping, continue stirring for 20min, at 10℃ Next, a solution of 1.9g (10mmol) indole-5-carboxylic acid methyl ester dissolved in 3.0mL N,N-...
Bismuth subcarbonate (basic bismuth carbonats) is an astringent antidiarrheal drug. After oral administration, it can coagulate the proteins on the surface of inflammatory mucous membranes to form a protective film, which has an astringent and protective effect and reduces inflammatory exudation. Some ...

How is methane prepared in the laboratory ? Video SolutionText SolutionGenerated By DoubtnutGPT To prepare methane (CH₄) in the laboratory, we can follow these steps: 1. Gather Materials: - Sodium acetate (C₂H₃NaO₂) - Sodium hydroxide (NaOH) - Heat source (like a Bunsen burner...
Wood ash is highly alkaline due to its high content of potassium carbonate. To use wood ash, collect the ashes from your fireplace or wood-burning stove and mix them with water. Stir the mixture well and allow it to settle for a few hours. The resulting solution can then be added ...
Adrian Madera I'm doing a research project where we analyzing the structure of sand after a certain process. To get a better idea of the internal structure of the sand, we use different colors to visualize the movement of the particles. However we can't actually observe that structure since...
