An 80°C aqueous solution containing 58 wt% sodium nitrate (NaNO3) is fed to a combination crystallization-settling unit operating at 25°C. The unit separates crystals from the remaining solution. If the feed to the crystallizer/settler unit is 1000 kg/hr, what is the production of dry crystals and the mass of the exiting solution? If the exiting solution is then fed to a second crystallizer-settler and 50 kg/hr of crystals were produced in the second unit, what is the operating temperature of the second crystallizer? See next page for solubility curve.
Line imperfection : Displacement with a curved boundary makes a mixed dislocation line at the boundary.
Nebulisation techniques: The accuracy, precision and detection limits of flame AAS depend on how the analyte sample is introduced into the atomiser. We need to transfer a repr
Q. What are the Chemical Properties of Halogens? Ans. he halogens have 7 valence electrons in their outermost shell. Note that 7 is one electron short of the octet.
Soda lime test - Nitrogen A pinch of an organic compound is heated strongly along with soda lime (NaOH + CaO) in a test tube. If ammonia gas acts, it depicts nitrogen.
Symmetry is a property of molecules having more than one atom of the same kind, with equal bond lengths and/or bond angles. As like the high symmetry of the SF6 molecule (Fig. 1. a

Acidic nature of monocarboxylic acids (1) Cause of acidic nature (a) A atom of carboxylic acid may be illustrated as a resonance hybrid of the following structures.
Enthalpy, H, is defined by the relationship H=U+pV. The enthalpy change, ΔH, for finite changes at constant pressure is given by the expression ΔH = ΔU+pΔV, so making the enthalpy
Compounds with similar molecular formula but different properties are known as Isomers and the phenomenon is known as Isomerism.
