Why do ionic compounds conduct electricity in an aqueous solution or when molten, but do not conduct electricity when in the solid-state? How can you make a 1.5 M HCl solution? Why we add HCl to H_2SO_4 during the experiment of iodometry? Explain why non-ionic compounds, such as ethan...
12. The process as defined by claim 11, said solvent solution comprising an aqueous or organic solution, or mixture thereof. 13. A process for eliciting an expectorant response in a mammalian organism in need of such treatment, comprising administering to such organism a therapeutically effective ...
Solubility Equation Determine the state or phase of each substance (gas=g, liquid=l, solid/non-soluble=s, aqueous/soluble=aq) in its undissociated form by using the solubility rules or a solubility table. KF(aq) + HCl(aq) = KCl(aq) + HF(aq) ...
Methodology Recently developed extraction techniques, including solid phase extraction, allowed all analytes to be isolated from the biodegradation cultures (aqueous and soil matrices), and subsequently analysed using novel high performance liquid chromatography鈥揺lectrospray ionization-multistage mass ...

• TCEP is stable in aqueous, acidic, and basic solutions. When TCEP is dissolved directly in water, the resulting pH is approximately 2.5. • TCEP is not particularly stable in phosphate buffers, especially at neutral or alkaline pH. Therefore, if TCEP is to be used in PBS buffers, pr...
作者: K. H. Lieser 展开 摘要: The dissolution of ThO2 which was heated to 750 and 1000°C (grain size 0.1 -0.2 mm) in mixtures of conc. HCl and various amounts of NH4F was investigated. The dissolution depends strongly on the mole ratio NH4F/ThO2. A minimum value of this ratio...
Na2S + HCl = NaCl + H2S is a Double Displacement (Metathesis) reaction where one mole of aqueous Sodium Sulfide [Na2S] and two moles of aqueous Hydrogen Chloride [HCl] react to form two moles of aqueous Sodium Chloride [NaCl] and one mole of solid Hydrogen Sulfide [H2S] Show Chemical St...
In addition, it is impossible that species present within solid or gaseous, the second term also disappear for aqueous species mass. By calculating the summation across phases of the advective and diffusive terms, the fluxes in Eq. (21) is expressed as Eq. (23) (Xu, 2001):(23)F=∑...
