What are the five properties of alkalis?

Chemical Properties of Alkalis

Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction.
Alkalis react with ammonium salts to form salt, water and ammonia gas.
Alkalis react with solution of metal salt to form another metal salt and hydroxide.

What are the uses of alkali?

Uses of common Alkalis

Sodium hydroxide is used to make paper, detergents and soap.
Potassium hydroxide is used by farmers to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries.

What are 5 properties of bases?

Chemical Properties of Bases

Bases change the colour of litmus from red to blue.
They are bitter in taste.
Bases lose their basicity when mixed with acids.
Bases react with acids to form salt and water.
They can conduct electricity.
Bases feel slippery or soapy.
Some bases are great conductors of electricity.

What are 3 properties of an acid?

Acids

Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current.
Acids have a sour taste.
Acids change the color of certain acid-base indicators.
Acids react with active metals to yield hydrogen gas.

What is the most important properties of base?

Bases have properties that mostly contrast with those of acids.

Aqueous solutions of bases are also electrolytes.
Bases often have a bitter taste and are found in foods less frequently than acids.
Bases also change the color of indicators.
Bases do not react with metals in the way that acids do.

What is a pH above 7 called?

pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. Water with a pH of five is ten times more acidic than water having a pH of six. As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

Acids react with bases to produce a salt compound and water.

What are the five physical properties of acids?

PHYSICAL PROPERTIES OF ACIDS:

Acids have a SOUR taste.
All acids are SOLUBLE in water.
Acids solutions turn BLUE litmus paper RED.
Acid solutions have a pH values < 7.

What are the types of base?

Types of Bases

Strong base – It is a compound that has an ability to remove a proton from a very weak acid.
Weak base – There is incomplete dissociation when in water.
Superbase – These bases are better at deprotonation when compared to a strong base.
