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 gene
During this process a large number of water molecules appear to fill the spaces between the enzyme and the DNA. Once the cognate (recognition) sequence is found, much of the water is excluded as a highly redundant number of contacts evolve between the enzyme and the bases and phosphodiester ...
How many {eq}ml {/eq} of a {eq}10.0\% {/eq} by volume stock solution of {eq}\rm HCl {/eq} must be diluted with enough water to make {eq}300\ ml {/eq} of a {eq}1.5\% {/eq} by volume solution? Dilution Equation:...
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’s a step-by-step on how to do this: Add 35 mL of deionized wa...
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 .
How to make dry HCl gas Question:How to make dry HCl gas Drying Gases:A gas can be dried effectively by putting it through substances that have high affinity to water and won't react with the gas. Such substances are anhydrous salts, and concentrated sulfuric acid.Answer...

You have 100 mL of a 12 M solution of HCl, and you need to dilute it to 1.5 M for an experiment. How many liters will your new solution be? How many mL of a 3.19M solution must be diluted to 1.24L to make a 0.204M solution?
Hence, the mass by mass percent is calculated by multiplying the ratio between the mass of the solute (in gram) and the mass of the solution (in gram) with 100.Answer and Explanation: Let's assume that the concentration of solution of {eq}\rm HCl {/eq} is given in mass by mass ...
