In Rubber Industry in which process chemists gets pure acid from diluted acid?

I would imagine that they would distill it.  Acetic acid boiles somewhere just above water if I remember correctly.  That's what I would try.  Actually I'd probably just buy some more.

6 moles of hydrochloric acid will react at a faster rate than 1 mole of hydrochloric acid because the solution will not dilute as fast as the smaller amount of acid- more acid to react with the Zinc.\n\nSounds good to me...

Milk, bleach, Maalox, Tums, chalk...anything that neutralizes an acid.

I think you can get it from chemical companies; those are the same places where science departments in schools get theirs.\nThat should give you an idea of where to look.

A strong acid is an acid that dissociates completely in an aqueous solution, ie. 100% hydronium ions.

It is not possible to obtain absolute alcohol by simple fractional distillation, because a mixture containing around 95.5% alcohol and 4.5% water becomes an azeotropic mixture. In one common industrial method to obtain 100% pure alcohol, a small quantity of benzene is added to rectified spirit and the mixture is then distilled. Because a small amount of the benzene used remains , the solution is carcinogenic. So production of absolute alcohol is done by desiccation using glycerol. Alcohol produced by this method is known as spectroscopic alcohol.

8. SO3 + H2O --> H2SO4 (sulphuric acid)\n9. Nitric acid - reducing agent\n    Sulphuric acid - concentrated H2SO4 can be used a drying agent, catalyst (in esterification); otherwise, in manufacturing of fertilizers, detergents, and as a battery acid in cars\n    Phosphoric acid - no idea...\n    Carbonic acid - in making carbonated drinks\n\nHope this helps :)

How are Rubber Bands made :\n\na) Mixing & Compounding\n\nThe rubber is mixed with various chemicals in required proportions depending on rubber content. This compounded mixture is then strained to ensure that there are no extraneous materials in compounded material.\n\nb) Extrusion\n\nThe compounded rubber is then put into an extrusion machine. This extrudes the rubber into tubing form using specific die heads to achieve a required diameter and wall thickness. The tubing is then cut into lengths and put onto mandrels of the same size / diameter.\n\nc) Curing\n\nThe tubing now on mandrels is put into an autoclave (oven) to ensure tubing reaches it's set form. The tubing is then blown off the mandrels for passing to the cutting area.\n\nd) Cutting\n\nThe tubing is then fed into rotary cutters to cut into designated cut widths of rubber bands.

I believe one commercially viable method is to add concentrated sulfuric acid.  The alkenes will form alkyl hydrogen sulfates, which are soluble in the H2SO4 (or in H2O).  Alkanes do not readily react with H2SO4, so they will not dissolve in the polar solvent.\n\nThis method of separating liquids based on selective solubilities is called extraction.  Since there is a chemical reaction between the solvent and the alkenes, this is technically called "reactive extraction."

phosphoric acid is the catalyst used in the synthesis.    Its a one to one molar ratio reaction.

it usually creates an acid  like HCl, HF, H2SO4

the answer depends on how many H+ need neutralising by the NaOH.\nassuming it is only 1 per molecule of the acid then you can use the following equations:\n\nno.of moles = (vol/1000)*concn\nno. of moles = (40.11/1000)*0.240 = 0.0096264\n\nno. of moles = mass(g) / RMM\ntherefore\n0.0096264 = 0.55 / RMM\ntherefore RMM = 0.55 / 0.0096264\nRMM = 57.134\n\nif you have 2H+ that need neutralizing then the molecular weight = 2*57.134 = 114.268 etc etc

Concentrated Sulfuric Acid, Concentrated Hydrochloric acid, Concentratic Nitric acid...almost all concentrated acids will read out at pH 1

Concentrated Nitric Acid and copper.  Be careful.  Nasty stuff... really!
