Formula of ‘Ortho-phosphoric acid’ is :
In IR spectra, unit of Y-axis is :
IR spectra : Y-axis : Transmittance & X-axis : Wavenumber
ICH is :
Volume of 1 m3 is equal to :
A water tank having dimension of 1 m x 1m x 1m ( l x b x h ) has capacity of 1000 Litres.
In a mixture of 600 mL solution, the ratio of methanol and water is 2:1.
To determine the quantity of water in the mixture, the calculation is :
If a solution is a mixture of A & B.
Then quantity of B present in the solution =
Total mixture volume x ( Ratio of B / Total ratio )
