give reasons 1)why is pure ethanoic acid known as gascial acetic acid
2)why is ethanol used as antifreeze?
3)why is oyacetylene flame used for welding purposes
​

Answer 1

Hey here is your answer,

1.) On cooling, pure ethanoic acid freezes to form flakes like ice. Since, it forms ice like crystals, that's why it is called glacial acetic acid.

2.)Ethanol serves to depress the freezing point of water below zero degrees Celsius (32 Fahrenheit).

3.)Oxy-Acetylene Weldinga fuel gas burns in oxygen, generating heat. ... The main purpose of the preheat flame in most flame processes is to achieve rapid, local heating. This imposes requirements on the combustion properties of the gas that is used.
