NOW THIS OUT !!!
It has a sour taste.
It turns blue litmus to red.
It turns methyl orange to red.
Acids are electrolyte.
Strong acids destroy fabric.
Strong acids cause burn on skin.
CHEMICAL PROPERTIES OF ACIDS

NEUTRALIZATION

An acid when reacts with a base, salt & water are produced. This reaction is called neutralization
HCl + NaOH è NaCl + H2O

HNO3 + NaOH è NaNO3 + H2O

HCl + KOH è KCl + H2O
REACTION WITH CARBONATES

Acid and carbonates are combined to produce salt, water and carbon dioxide
MgCO3 + 2HCl è MgCl2 + CO2 + H2O

CaCO3 + 2HCl è CaCl2 + CO2 + H2O

Na2CO3 + H2SO4 è Na2SO4 + CO2 + H2O

CaCO3 + H2SO4 è CaSO4 + CO2 + H2O

REACTION WITH BICARBONATES

Acid and bicarbonates are combined to produce salt, water and carbon dioxide
NaHCO3 + HCl è NaCl + CO2 + H2O
REACTION WITH METAL

With Zinc:
Zn + 2HCl è ZnCl2 + H2
With Aluminum:
2Al + 6HCl è 2AlCl3 + 3H2
Reaction with iron oxide:
6HCl + Fe2O3 è 2FeCl3 + 3H2O

Hey Guys!! Its very interesting!!!! Twisted Evil  Twisted Evil  Twisted Evil



Chemical Properties of Acids and Bases

As acids and bases are highly corrosive and reactive substances it is important to understand their reaction and responses on substances commonly found around us. It helps us to understand the outcomes of using them in daily life. Let see the different acids and bases.
 
Some common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H2SO4) and Nitric acid (HNO3). Some of the lesser used acids are Acetic acid (CH3COOH), Hydrofluoric acid (HF), Carbonic acid (H2CO3). Hydrofluoric acid is a highly corrosive acid and is used to etch glass. Some acids are found in nature, like citric acid in certain fruits. These acids are called 'organic acids'.
Cool Cool cheers Basketball lol!
