Elements that can react with acid and alkali are called amphoteric eg. Zn, Al, etc.
When an acid and a base or an alkali react they form corresponding salt and water.
Stomach acid oviasly cantains acid so when acid and alkali are mixed neutralasation happens.
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
The products are a salt and water.
An Alkali is also a base. So, when reacted with an acid forms a salt and water as products
If they react until neutral then the pH will be 7. However, if there is an excess of acid the pH will be <7 and vice versa.
when alkali which can also be called a base reacts with an acid, a salt is usually form plus water. it is called a neutralization reaction.
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
A salt and water.
neutralization
Neutralisation, and yes that is how you spell it
