Why H3PO3 is a diprotic acid? Give reason with structure .

By ankushmaster on December 21, 2020April 30, 2021

Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its structure. Here it have only two hydroxyl groups that is -OH groups, and the hydrogen atoms joined to these only are ionisable. So only these

How the eye accommodates to light ?

By ankushmaster on September 6, 2020March 29, 2021

#accomodation #of #light In our day to day life we face various exposure to light. The intensity of rays vary from source to source some are intense and some are very low. Here i am going to share about the working of Iris of eye. Iris is basically like the shutter of cameras, it adjusts

What will be the volume of water when it is heated from 0 degrees Celsius to 10 degrees Celsius?

By ankushmaster on May 13, 2020December 17, 2020

According to CHARLES LAW “At constant pressure, The volume of a given mass of a gas increases or decreses by 1/273 of its volume at 0 ͦ degree C for every one degree centigrade rise or fall in temperature”. Vol at 10 = vol at zero + 10 x vol at zero/273

How many oxygen atoms are there in 90g of H2O molecule?

By ankushmaster on May 13, 2020June 22, 2021

1 molecule of H2O has 1 atom of oxygen. Firstly we will calculate the number of atoms in 90g of H2O. we will explain it in two steps:- Step I:- No.of moles of H2O = given mass / molar mass No. of moles = 90/18 = 5 moles No. Of molecules = No. of moles

Distillation and fractional distillation.

By ankushmaster on April 22, 2020August 1, 2021

Distillation is a type of separating process in which two miscible liquids are separated from each other by using their different boiling points. the one with lower boiling point , boils first and its vapours are passed through a condenser for cooling and droplets are received on the other side in a beaker. this process
