Can we Use fajans method to determined the exact concentation of a approximate 0.01 M hcl solution?
No, Fajans method is not suitable for accurately determining the concentration of a dilute 0.01 M HCl solution. Fajans method is typically used for determining the concentration of anions in a solution, specifically for halide ions in the presence of a specially selected indicator. For accurate determination of the concentration of a 0.01 M HCl solution, titration with a suitable base such as sodium hydroxide would be more appropriate.
Industrial preparation of sodium hypochlorite by hookers process?
That depends on the volume of 0.1 N sodium hypochlorite you wish to make. To make 1 liter, place 0.2 moles NaClO in sufficient water to make 1 L. The mass of 0.2 moles will be 0.2 x molar mass =0.2 x 74.4 = 14.9 g = 15 g (to 1 significant figure). So, dissolve 15 g NaClO in sufficient water to make a final volume of 1 liter.
What method is used to prepare potassium chloride?
Potassium chloride is typically prepared by reacting potassium hydroxide with hydrochloric acid, resulting in the formation of potassium chloride and water. Alternatively, it can be obtained from the process of fractional crystallization of a solution containing potassium and chloride ions.
How do you calculate the percent chloride with the volhard method?
To calculate the percent chloride using the Volhard method, you measure the excess silver nitrate used to titrate the chloride ions in the sample. You then use the volume of excess silver nitrate and the molarity of the silver nitrate solution to calculate the moles of chloride present. Finally, calculate the percent chloride by dividing the moles of chloride by the sample weight and multiplying by 100.
What is co precipitation method?
this method is used for making the compound in gel form
How do you determine the concentration of concentrated hydrochloric acid?
Method: titration with a standardized solution of sodium (or potassium) hydroxide.
Which is the best method of estimate acetic acid in pharmaceutical and commercial preparation?
The best method for estimating acetic acid in pharmaceutical and commercial preparations is typically titration using a standardized sodium hydroxide (NaOH) solution. This method involves titrating a known volume of acetic acid solution with NaOH until a color change occurs, indicating neutralization. The volume of NaOH used can then be used to calculate the concentration of acetic acid in the sample.
How will prevent salting point in the preparation of aromatic waters?
the methods of preparing aromatic waters are: 1. by distillation 2. by solution 2.1.by direct solution 2.2. by alternate solution
What is the most common chemical method for removing hydrogen ions in a solution?
The most common chemical method for removing hydrogen ions in a solution is by using a base, such as sodium hydroxide or potassium hydroxide. Bases, due to their alkaline nature, can react with hydrogen ions (protons) to form water molecules, effectively neutralizing the acidity of the solution and increasing its pH.
Explain about Condutometric titration's of copper sulphate with sodium hydroxide?
Condutometric titration of copper sulfate with sodium hydroxide is a method used to determine the concentration of copper ions in a solution. By adding sodium hydroxide to a solution of copper sulfate, a white precipitate of copper hydroxide is formed. The end point of the titration is reached when all the copper ions have reacted with the sodium hydroxide, leading to a sudden increase in the solution's conductivity, which can be detected using a conductivity meter.
What is a raise of 1 percent on 64400?
644 Solution Method: 1% * 64400 = ? .01 * 64000 = 644
What purification method wa used in the experiment preparation of iodoform?
The purification method used in the preparation of iodoform in the experiment is recrystallization. This process involves dissolving the impure iodoform in a solvent at an elevated temperature and then slowly cooling the solution to allow pure iodoform crystals to form and separate from the impurities.
How is sodium hydroxide manufactured?
Sea water is a free and rich source of sodium chloride. Electrolyzing a sodium chloride solution is a popular method of manufacturing sodium hydroxide. The same method is used in industrial method, and another advantage is that the manufacturing of two other important substances, namely hydrogen and chlorine gases.
How can you test for hydroxide ion?
One way to test for hydroxide ions is by using red litmus paper. If the red litmus paper turns blue when dipped into a solution, it indicates the presence of hydroxide ions. Another method is to use a pH indicator, such as phenolphthalein, which changes color in the presence of hydroxide ions.
Why calcium is not used in the lab preparation of hydrogen?
Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.
Which is 25 percent of 50?
12.5 ------------------- Solution Method: ? = 25% of 50 ? = 25%/100 * 50 ? = .25 * 50 ? = 12.5 <-- this is your answer ====== Answer 1: 25 percent of 50 is 12.5.
What is the Name the method used to prepare insoluble salts?
The preparation of insoluble salt can be done by PRECIPITATION METHOD
