1 · (D) The acid strength decreases whether X is a nonmetal or a metal. Examples: [Pb(OH)Cl] – Basic lead chloride, [Mg(OH)Cl] – Basic magnesium chloride, etc. Na2SO4, or sodium sulfate, is a salt formed in a neutralization reaction with sulfuric acid (an acid) and sodium hydroxide (a base).
the strength with which a protein binds to a specific metal ion and consequently its purifiion. This factor should thus be considered when developing and optimizing a purifiion strategy using immobilized metal affinity chromatography. Fig 1. HiTrap Chelating
Corrosion data for a various stainless steels in an extensive range of media. The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables
Calculations The concentration units for chemical standard solutions used for ICP appliions are typically expressed in µg/mL (micrograms per milliliter) or ng/mL (nanograms per milliliter). Therefore, if we have a solution that is 1000 µg/mL Ca +2 and know or measure the density to be 1.033 g/mL then the ppm Ca +2 = (1000 µg/mL) / (1.033 g/mL) = 968 µg/g = 968 ppm.
Minimum static strength per granule is 7 N. Urea is classified as environment-friendly fertiliser. Sodium Sulphate Speckles Detergent colorful speckles and novelty shaped speckles, which are detergent raw materials and 1%-3% of them are used directly into detergent powder to increase a visual effect.
To achieve osteoconductivity, Ti–0.5Pt and Ti–6Al–4V–0.5Pt alloys were hydrothermally treated at 200 C in 10 mmol/l CaCl2aqueous solution for 24 h (HT-treatment). We
No reaction for caCl2 and HCl will take place as both have the same anion in them >The same anion is Cl- which will not cause any further reaction between them. the balanced chemical equation

Lattice energy is an estimate of the bond strength in ionic compounds. It is defined as the heat of formation for ions of opposite charge in the gas phase to coine into an ionic solid. As an example, the lattice energy of sodium chloride, NaCl, is the energy released when gaseous Na + and Cl – ions come together to form a lattice of alternating ions in the NaCl crystal.
