Any Group(I) metal alkali
Lithium hydroxide (LiOH)
Sodium hydroxide (NaOH) The commonest)
Potassium hydroxide (KOH)
Rubiudium hydroxide (RbOH)
Caesium hydroxide (CsOH)
Also Group(II) metal hydroxides #e.g.
Calcium hydroxide ( Ca(OH)2 ).
The will all neutralise hydrochloric acid
Here is the general eq'n
MOH + HCl = MCl + H2O ( where 'M' is the given metal).
Neutralization
Neutralization
Hydrochloric acid will react with permanganate, but more violently than sulfuric acid, leading to inaccurate results. Additionally, hydrochloric acid will produce chlorine gas, which can be hazardous. It is best to use sulfuric acid for permanganometric titrations to ensure accurate and safe results.
Copper sulfate is not typically used as a catalyst in the reaction between zinc and hydrochloric acid. The reaction between zinc and hydrochloric acid is a single displacement reaction where zinc displaces hydrogen from hydrochloric acid to form zinc chloride and hydrogen gas. In this reaction, the presence of copper sulfate would not act as a catalyst to speed up the reaction.
In the Stomach. The first part of digestion is chewing in the mouth and mixing with saliva. Then swallowing. THen when in the stomach, the stomach walls naturally secrete hydrochloric acid and pepsin into the 'mix'. The stomach operates at pH = 1. This is a natural process, and you DO NOT swallow hydrochloric acid.
Neoprene or teflon lining is the most suitable for hydrochloric acid.
acid
Hydrochloric Acid
It works by neutralising the hydrochloric acid (HCl) from the stomach, because it is not normal to have a surplus of acid in your stomach. This is a chemical reaction of neutralization for the control of pH. The indigestion tablet has alkaline in them.
Neutralization
Broccoli is a Brassica so grows best in alkali soil.
Any acid can be used to neutralize a base such as sodium hydroxide. If you have a concentrated solution of sodium hydroxide, you could neutralize it most efficiently with a strong acid such as hydrochloric acid. You can also neutralize it with Coca Cola, or vinegar, or many other acidic chemicals, but it would require a larger amount than if you used hydrochloric acid.
Neutralization
The stomach secretes hydrochloric acid. The acid is produced by special cells called parietal or oxyntic cells. The pH of stomach acid is between 1 - 2. For more details see: http://en.wikipedia.org/wiki/Gastric_acid

Pepsin works best in an acidic environment, so the substance that must be present in the stomach for pepsin to work best is hydrochloric acid. This acid helps to activate pepsinogen into its active form, pepsin, which is responsible for breaking down proteins in the stomach.
