What is gravimetric factor?
A gravimetric factor converts grams of a compound into grams of a single element. For example, we'll find the gravimetric factor of Cl in AgCl. Use the atomic mass of Ag(107.868) and the atomic mass of Cl(35.453) and add them together to get 143.3. Then divide 35.453 by 143.3 to get .2474. .2474 is the gravimetric factor of Cl in AgCl.
How do you turn 1N of HCL into 0.001N of HCL?
By dilution (1000x) with water: Take 1.0 mL 1.0N HCl and add up to 1000 mL with pure water.
How do you make 1M HCl from 36M HCl?
To dilute 36M HCl to make 1M HCl, you need to add 1 part of 36M HCl to 36 parts of water. So, for example, if you want to make 1 liter of 1M HCl, you would mix 27.8 ml of 36M HCl with 972.2 ml of water. Always remember to add acid to water slowly and with stirring to prevent splattering.
How do you dilute HCl for preparing H2S gas?
To dilute HCl for preparing H2S gas, you can slowly add concentrated HCl to water, as it is exothermic and can generate heat. Be cautious and always add acid to water, not the other way around. Diluted HCl can then be used to react with a sulfide salt to liberate H2S gas.
What you add to an experiment to make a change?
You add an independent variable to an experiment to make a change. This variable is manipulated by the researcher to see if it has an effect on the outcome of the experiment.

How do you prepare 1N hcl to 6N hcl?
To prepare 6N HCl from 1N HCl, you can dilute the 1N HCl by adding 6 times the volume of water to the 1N HCl solution. For example, mix 1 volume of 1N HCl with 6 volumes of water to get a final concentration of 6N HCl. Make sure to add acid to water slowly with stirring to avoid splashes and heat generation.
Methods to determine silica content in sodium silicate?
firstly, take 1ml of sodium silicate and add 99ml of water. titrate it with 0.5N HCl and use 1 drop phenophthalein as indicator. the amount of HCl used is converted to gram by using the density and molecular weight calculations. 1.177gm of HCl used for 1 gm of sodium oxide, calculate by multiplying your HCl used for your sodium oxide. now take 10ml of silicate and weigh it in grams and heat it at 180 degrees celsius for 2 hours to get solid content (water evaporated) deduct the value of sodium oxide from total solid content obtained. this is the value of silica in your sodium silicate.
How to prepare HCL solution?
To prepare a hydrochloric acid (HCl) solution, you can dilute concentrated hydrochloric acid with water. Always add the acid to water slowly while stirring, never add water to acid, as it can cause splattering. Be sure to wear appropriate protective gear and work in a well-ventilated area when handling HCl.
How do you write HCl in water?
When added to water, hydrogen chloride gas (HCl) will dissolve and form hydrochloric acid. This reaction results in the release of heat and is exothermic. It's important to add HCl slowly to water and stir gently to prevent the solution from splashing or boiling.
How do you make 50 percent HCL?
To make 50% hydrochloric acid (HCl), you would need to dilute concentrated hydrochloric acid (typically around 37%) with water. Measure out the appropriate amount of concentrated HCl and add an equal volume of water to achieve the desired concentration. Always add acid to water slowly and with stirring to prevent splashing or overheating.
How do you prepare 500 ml 1N hcl from 10N HCl?
For 1 Liter you should take 88.8 mL concentrated HCL (be carefull) and add it to 900 mL water, and finally - after mixing- fill this up to 1000 mL with distilled water. (REMEMBER: ALWAYS ADD ACID TO WATER! -1N in 250 ml : add 22.2 mL to about (or less than) 225 mL water and dilute to final volume = 0.25L
How do you prepare 0.5M HCL from 37 percent HCL?
Depending if you want your % to be in volume and you have 100 mL then add 212.5mL to the HCl. If you want it by mass and you have 100g of HCl then add 212.5 g of water which is about 212.5 mL anyways. #swag
