Re: How to prepare a dilute Hcl « Reply #3 on: March 09, 2015, 07:36:28 AM » I just quickly looked at this and wanted to add - never add water to acid - add the acid to water.The sulphuric acid will generate heat - so when you add to water be very careful. Logged ...
Prepare 100 mL of 10 % w/w HCl from 37% concentrated HCl (density of 37% HCl = 1.19 g/ml). Describe how you could prepare 123 mL of a 1.2 M HCl solution from a 2.0 M HCl solution. Describe how to prepare 50 mL of a 0.20 M HCl solution from a 0.50 M HCl so...
Why can't Na be used to prepare H2? How would you prepare a carboxyl-terminated polyester? how do you oxidize ch3ch2c(oh)(ch3)ch3 Describe the preparation of 1.0 L of 0.5 M HCl, starting with conc. HCl (12 M). Explain how you could prepare 1.0 L of a 0.02 M Na2CO3 solution. ...
To prepare 5M HCl, the dilution ratio we need is 5/12 = 0.416. So, we need 0.416 parts fuming HCl and 0.584 parts water to generate 5M HCl. In simple lab-friendly terms, this means diluting 42 mL of fuming HCl into 58 mL of water to generate 100 mL of our final 5M HCl. Here’...
Let V be initial volume Then mol of HCl = constant 2 xx V = 1 xx 0.5 " "rArr" " V =0.25 L Volume of water added =1 - 0.25 = 0.75 L .
Dow's process is a method to prepare phenol. The reactant chlorobenzene is heated with aqueous sodium hydroxide at temperature 623K and 300atm to get sodium phenoxide ion. Then in the next step sodium phenoxide ion is treated with Dilute HCl which gives the final product as phenol. What is...
How much water should be added to 10ml of 6 alcohol solution to reduce the concentration to 5? How many milliliters of water must be added to 350 mL of 0.840 M HCl to dilute the solution to 0.250 M? How many milliliters of water ...
PVC is chemically inert. Dilute acids, dilute alkalis, and aliphatic hydrocarbons are all resistant to it. Some layers are inflated or attacked by aromatic and chlorinated hydrocarbons, esters, some aromatic ethers and amines, and nitro- compounds. Some layers swell or are assaulted by ketones; ...
How many grams of HCL are required to prepare 200.00 ml, 0.55 M HCL solution? How many grams of HCl are required to prepare 300 mL of a 0.7 M HCl solution? How many grams of HCl are contained in 3.00 L of the solution with a concentration of 0.0129 M HCl ? How many grams of HCl...
How much of a 12.0 M hydrochloric acid solution would you dilute to prepare 50.00 mL of 6.00 M HCl? How many grams of HCI are there in 100.0 mL of concentrated HCl which is approximately 12.1M and ...
