Barium sulfate is an inert substance that does not readily react with other substances. It can react with strong acids to form corresponding barium salts and sulfuric acid, for example: BaSO4 + 2HCl → BaCl2 + H2SO4 Applications of Barium sulfate Barium sulfate has extensive applications in the...
How could you separate BaSO4 from NaCl? Is it correct to describe sodium chloride as both metal and a salt? Sodium metal is soft whereas sodium chloride is very hard. Explain why. NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. Explain ...
This is a monobasic acid. On treatment with sodium nitrite and dilute hydrochloric acid at 273K, one mole of X liberates one mole of N2, and on addition of aqueous BaCl2, the resulting solution yields one mole of BaSO4 per mole of X taken initially. Deduce the structure of X.尽快,...
Classify each of these soluble solutes as either a strong electrolyte, a weak electrolyte, or a non-electrolyte a) Sulfuric acid- H2SO4 b) Potassium hydroxide- KOH c) Carbonic acid- H2CO3 d) Ammonia- NH3 e) Potassium chloride- KCl f) Butanol- C...
Why is BaSO4 used in this procedure? solubility is 1*10-5 mol/liter or 0.00233 g/L Ba 137 g/mol S 32 g/mol O 16 g/mol 137+32+64 =233g/mol 233 g/mol*10-5 mol/L Kidney stones are either calcium phosphate, Ca3(PO4)2, calcium oxalate, CaC2O4 or uric acid, C5H4N4...
In accordance with the method of preparing the tritium-traced saxitoxin, presented by the instant invention, saxitoxin should be introduced into an isotope exchange reaction in the form of a free base or in the form of a salt thereof with acid. In order to carry out the reaction, a source...
Radioactive decay rate is first order with respect to the reactant. The integrated rate law of a first order reaction is: A=Aoe−kt where k is the rate constant. The half-life of the reaction is related to the rate constant:
