You drop conc. HCl into conc. H2SO4 - this releases HCl gas which you can bubble through dry ether... Or, you use an HCl cylinder.
Preparing 1N HCl for 1L. 1N=1M in HCl. Conc. HCl= 12M M1V1=M2V2 12*V1=1*1000 V1=1000/12 V1=83.33ml 1N HCl= 83.33ml of Conc. HCl in 1L of water 2N HCl= 167ml of Conc. HCl in 1L of water.
1N - conc will change the pH too quickly. You might want to consider 0.1molar for finer adjustments.
According to I.P. 1996
25 ml conc. Hcl(11.6 n)+91 ml distilled water
Copper II oxide reacts with conc. HCl to give CuCl2 but no gas. Bot Manganese dioxide reacts with conc. HCl to give a greenish yellow gas i.e. Chlorine.
The HCl will be brought up to volume with Dionized H2O
HCl liberates 1M of H+ Ions per mole of HCl so 0.034M HCl = 0.034 M H+ Ions as pH = -log10 [H+] where  means the conc. pH= -log10 [0.034]
Few pieces of Metallic tin and conc HCl
dilute 1.7 ml of Conc. HCl to 1000 ml with water
Reagents Needed: diphenyl carbazide conc. HCl ethanol Method: 1. Dissolve 0.5g of diphenyl carbazide in 5mL of conc HCl. 2. Prepare a solution of 50%(v/v) ethanol by mixing 50mL 95%(v/v) ethanol and water. 3. Transfer the diphenyl carbazide solution in HCl to the 50% ethanol and mix.
It is safe to swim after adding hydrochloric acid to swimming pool. but in a small quantity like for a pool just a liter of dil. HCl (0.1N) . But if you use conc. HCl , then there may be chances of skin burn or blisters etc. to the skin. It mainly depends on concentration. and amount of water is added. DO NOT ADD conc. HCL to the water. There will the chances of bursting.
HCl activates the enzyme pepsinogen, which then undergoes autocatalytic cleavage and becomes pepsin. Pepsin digests proteins in the stomach.
10N HCl is equivalent to 10 M HCl and the solution will contain 10 moles of HCl per 1 liter or solution. Depending on the volume of solution, the preparation will vary. To prepare 1 liter, place 360.5 g of HCl in a total volume of 1 L. To prepare 1 L from concentrate HCl (12.1 M) dilute 833 ml of conc. HCl to 1 L.
Sulphur dioxide + ethylene --> mustard gas orthiodiglycol + a chlorinating agent (conc. HCl or some phosphorus trichloride) --> mustard gas.
Aqua regia or royal water (mixture of conc. HCl and conc. HNO3 in the ratio of 3:1 by volume) 3HCl + HNO3 = NoCl+2 H2O + Cl . NoCl= nitrosyl chloride Cl= nascent chlorine
300 mg of orcinol in 100 ml of conc. HCl and 0.25 ml of ferric chloride solution (10g / 100ml ).
Acids protonate the carbonyl oxygen, making the carbonyl group more electrophilic. Since the reaction is equilibrium limited, water is avoided, which is why conc sulfuric is typically used rather than conc HCl. p-toluenesulfonic acid (pTsOH) is also used frequently.
Aqua regia:a mixture of concentrated HCL(hydrochloric acid)&conc. HNO3(nitric acid) in ratio of 3:1 ,can dissolve gold.
Mixture of Conc. nitric acid and Conc. Sulphuric acid
Normaly HCl is supplied 35.5% w/w in 2.5 ltr bottles. Its Specific gravity is 1.18 g/ltr. First we convert weight to volume using provided inputs. Now taking all units in CGS g HCl =2500 X1180 =2950 g HCl Further for 35.5 % (means 35.5 in 100) then g HCl =0.355X2950=1047.25 Mole HCl=1047.25/36.5=28.69 Mole Normality and molarity will be same in case of HCl. Molarity=28.69/2.5=11.476 Approx.11.5
I'm not quite sure if you've formulated your question correctly. Hydrochloric acid, HCl(aq), is what it is, whether cold or hot. When you dilute concentrated HCl the dilution reaction releases a lot of heat (more of it the more conc. the HCl is to begin with). Depending on how much you are diluting may cause the reaction vessel to feel warm (or even hot) to the touch. When you dilute concentrated HCl you should determine how much water it will take and then add the HCl slowly to most of the water required. The water has a high specific heat and can absorb the heat being generated (but you still add the acid slowly). You don't add the water to the conc. HCl. The heat generated can be enough to pretty much instantaneously boil the water and it can splatter in your face (carrying some of the acid with it) causing a severe burn.
0.16 grams of BaF2 only soluble in 1 litre of water. But it can be dissolved using Nitric acid and Hydrochloric acid. 0.5 g BaF2 + 5 ml Conc. HCl + 5 ml of Conc. Nitric acid - boil it until effervescence ceases. Add some water. You get clear solution.
