    The solubility product is a heterogeneous equilibrium constant, a specific form of the equilibrium constant. It is relevant in saturated solutions in which an ionic compound has not fully dissolved. Solubility products change with temperature, so the temperature at which a solubility product was measured must always be quoted.

    According to the Heisenberg's Uncertainty principle, it is impossible to determine simultaneously the exact position and the exact momentum of an electron (microscopic particle) with absolute accuracy and certainty. Mathematically, it can be represented as Δx × Δpx ≥ h/4pie Or, Δx × Δ(mvx ) ≥ h/4pie Or, Δx × Δvx ≥ h/4pie ×m Where, Δ x is the uncertainty in position Δ vx is the uncertainty in velocity Δ px is the uncertainty in momentum If the uncertainty in position (Δx) is less, then the uncertainty in momentum (Δpx ) would be large. On the other hand, if the uncertainty in momentum (Δp) is less, the uncertainty in position (Δx) would be large.

    1)The cathode rays are made up of material particles. 2)They carry -ve charge. Hence, the above experiment explains that, cathode rays are negatively charged material particles called as ELECTRONS.

    2Thank You

    Cathode Ray Experiment: This is also known as discharge tube experiment , because it was initially done in a discharge tube .This experiment was carrried out by Willium Crookes in 1879 to explain the properties of negatively charged particles and conduction of electricity through gases in low pressure. Latter, the experiment was used by J.J Thomson to explain the nature of electron and discovery of electron. Mr. Cookes , studied that, electricity can be conducted through gases when at low pressure. Experiment: According to the above theory, a discharge tube (which is a long glass tube) is taken about 60cm long and sealed that tube at both the ends and fitted with two metal electrodes. It has a side tube fitted with a stop - ****. Now , this tube is connected to a vaccum pimp and the pressure inside the tube is lowered by using this pimp and maintained to 0.01 mm. A high voltage electricity of about 10,000 V is applied between the electrodes and the result is abtained. Observation: 1)some invisible rays are emitted from the -ve cathode which makes a greenish glow at the opposite wall of discharge tube. 2)The rays coming from cathode , produces a shadow if a solid object is placed between the two electrodes; which explains that cathode rays travel in a straight line. 3)If an external electric field is applied, the cathode rays are deflected towards the +ve anode , so the rays must carry a negative charge. 4)They strike the metal foils and causes heating effect 5)They cause ionization of the gas in the discharge tbe and produce X-rays when fall over hard metals like Tungstun, Molybdenum etc. They affect the photographic plates.

    Steric hindrance is the slowing of chemical reactions due to steric bulk. It is usually manifested in intermolecular reactions, whereas discussion of steric effects often focus on intramolecular interactions. Steric hindrance is often exploited to control selectivity, such as slowing unwanted side-reactions.

    Cu+ ion can be both, an oxidizing and reducing agent. It is reducing agent towards stronger oxidants that Cu+ ions are by themselves (i.e. it reduced H2O2, KMnO4 as they are much more powerful oxidants then Cu+ ion) and it is an oxidizing reagent toward strong reducing compounds/elements such as Na. Zn, N2H4.
