A colourless gas 'A' with a pungent odour is highly soluble in water and its aqueous solution is weakly basic. As a weak base, it precipitates the hydroxides of many metals from their salt solution. Gas 'A' finds application in detection of metal ions. It gives a deep blue colouration with copper ions. Identify the gas 'A' and write the chemical equations involved in the following : (i) Gas 'A' with copper ions (ii) Solution of gas 'A' with ZnSO_(4) solution.

A hydrogen-like gas is kept in a chamber having a slit of width d = 0.01 mm . The atom of the gas are continuously excited to a certain energy state . The excite electron make transition to lower levels , From the initial excite state to the second excited state and then from the second excited state ground state. In the process of deexcitation, photons are emitted and come out of the container through a slit. The intensity of the photons is observed on a screen placed parallel to the plane of the slit . The ratio of the angular width of the central maximum corresponding to the two transition is 25//2 . The angular width of the central maximum due to first transition is 6.4 xx 10^(-2) radian. Find the atomic number of the gas and the principal quantum number of the inital excited state.

Paramagnetism is a property due to the presence of unpaired electrons. In case of transition metals, as they contain unpaired contain unpaired electrons in the (n-1) d orbitals , most of the transition metal ions and their compounds are paramagnetic . Paramagnetism increases with increases in number of unpaired electrons. Magnetic moment is calculated from 'spin only formula' Vz mu=sqrt(n(n+2)) B.M n="number of unpaired electrons" Similarly the colour of the compounds of transition metals may be attributed to the presence of incomplete (n-1) d sub-shell. When an electron from a lower energy of d-orbitals is excited to a higher energy d-orbital, the energy of excitation corresponds to the frequency of light absorbed. This frequency generally lies in the visible region. The colour observed corresponds to complementry colour of the light obserbed. The frequency of the light absorbed is determined by the nature of the ligand. Titanium shows magnetic moments of 1.73 BM in its compound. What is the oxidation state of titanium in the compound?
