A base react with an acid to form only

• Salt

• Water

• they don't react

• Salt and water

What is the difference between base and alkali

• Alkalis are water insoluble bases

• Alkalis are water soluble bases

• Both are same

• Alkali react with acids while bases don't.

Which of these general equations is/are correct?

• acid + base → salt + water

• acid + metal carbonate → salt + water + carbon dioxide

• acid + metal → salt + hydrogen

• acid + metal oxide → salt + water

• acid + metal hydroxide → salt + water
