HCl and Mg are two chemicals. There is no variable involved - independent or otherwise!
n+1\100=4+1\100=5\100=.05
520 ml of HCl in 480 ml of water=1000ml = 5 N
Mix approx. 12 mL of HCl 30 % in 1 L water.
add 5 ml of 37% HCl to 495 ml Water. This is 0.12 N ;)
I'm not sure about the 37 thing but here is from NIOSH method in how to prepare 6N HCL -pipette 25.64 mL of 11.7 N (37% HCL fuming) to 50 mL volumetric flask and top up with distilled water GOOD LUCK Always add acid to water.
10.82
Prepare HCl 1 M by HCl concentration 37 % HCl concentration 37 % have density =1.19 g/ml HCl 1 M use HCl 37 % 82.81 ml make volume with water to 1 liter
7.3gm
0.2 N HCl solution means 0.2 equivalents of HCl dissolved in 1 litre of water. Normality = Molarity x n-factor => Molarity =Normality/n-factor=0.2/1=0.2 M 0.2 moles should be present in 1 litre of solution. 0.2moles =0.2 x 36.5 = 7.3 grams of HCl =>Dissolve 7.3 grams of HCl in 1 litre if water to get a 0.2N solution.
You drop conc. HCl into conc. H2SO4 - this releases HCl gas which you can bubble through dry ether... Or, you use an HCl cylinder.
100 M HCl don't exist.
0.1 M HCl =============
To prepare 0.1M methanolic HCl: 8ml water in 1000ml vol. flask. slowly add 8.6ml HCl. vol. make upto mark with methanol.
