An aqueous solution is $1.00$ molal in $\text{KI}$. Which change will cause the vapour pressure of the solution to increase?
Coconut milk factor is:
The correct option for the value of vapour pressure of a solution at 45 °C with benzene to octane in a molar ratio 3:2 is: [At 45 °C vapour pressure of benzene is 280 mm Hg and that of octane is 420 mm Hg. Assume Ideal gas]
When neutral or faintly alkaline $KMnO_4$ is treated with potassium iodide, iodide ion is converted into 'X'. 'X' is:
Vapour pressure of chloroform ($CHCl_3$) and dichloromethane ($CH_2Cl_2$) at 25°C are 200 mm Hg and 41.5 mm Hg respectively. Vapour pressure of the solution was obtained by mixing 25.5 g of $CHCl_3$ and 40 g of $CH_2Cl_2$ at the same temperature will be: (Molecular mass of $CHCl_3$ = 119.5 u and molecular mass of $CH_2Cl_2$ = 85 u)
Identify the incorrect statement among the following:
Acidified $K_2Cr_2O_7$ solution turns green when $Na_2SO_3$ is added to it. This is due to the formation of:
Which of the following ions will exhibit colour in aqueous solutions?
Which of the following ions displays the d-d transition and paramagnetism?
Assertion (A): Ionization enthalpy increases along each series of transition elements from left to right. However, small variations occur. Reason (R): There is a corresponding increase in nuclear charge which accompanies the filling of electrons in the inner $d$-orbitals.
Which of the following series of transitions in the spectrum of hydrogen atom fall in visible region?
Which of the following statements is not true for halogens?
Among the following, the incorrect statement regarding interstitial compounds is:
Gadolinium has a low value of third ionisation enthalpy because of:
The most acidic compound among the following is:
A paramagnetic molecule among the following is:
