Question

What are the 5 properties of bases? ​

Answer 1

Answer:

Bases are bitter to taste a bitter taste is characteristic of all bases.

Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis. Some examples of soluble bases or alkalis are sodium hydroxide, potassium hydroxide, and calcium hydroxide.

Like acids, bases can be strong or weak.

Strong bases are very corrosive and can burn the skin.

These bases should be handled carefully. Caustic soda or sodium hydroxide (NaOH) and caustic potash or potassium hydroxide (KOH) are strong and corrosive bases.

On the other hand, copper hydroxide [Cu(OH)2], zinc hydroxide [Zn(OH)2], and ammonium hydroxide (NH4OH) are weak bases

The solutions of bases in water give a soapy touch. When dissolved in water they produce hydroxide ions (OH–) in solution.

Answer 2

$\mathtt{\huge{\underline{\pink{Answer :-}}}}$

A base is a substance which when dissolved in water gives hydroxide OH- ions in the solution.

NH4OH + HCL ➝ NH4Cl + H2O

The bases which are soluble in water and gives Hydroxide ion in the aqueous solution are called Alkalies .

NH3 + H2O ➝ NH4OH ➝ NH4+ + OH -

Base is a substance which neutralizes and acid therefore sodium carbonate Na2Co3 and Sodium Hydrogen Carbonate NaHCO3 are also considered as base ,NaOH and acid H2CO3 are called carbonic acid .

• Bases have bitter taste .

Action on Litmus :-

Bases are having pH more than 7 which changes the red litmus to blue.
