The structures of the ions formed by several alkyl pyrroles in hydrochloric acid are deduced from proton resonance spectra. Basicity values for three alkyl pyrroles are determined from ultraviolet spectra of their salts in buffer solutions. An attempt is made to estimate the basicity of other ...
Benzyl chloride is the starting material for a large number of industrial syntheses. The first preparation of it involved not the chlorination of toluene, however, but the reaction of benzyl alcohol with hydrochloric acid. Physical Properties Benzyl chloride is a colorless liquid which fumes in ...

The influence of hydrochloric or sulphuric acid treatment on the electro-physical properties of superthin basalt fiber (STBF) made from Armenian basalt rocks was studied. Specific electric resistance for direct and alternating currents, dielectric parameters of εand εwere measured. It is shown that...
DMSO is also stable in the presence of concentrated sulfuric or hydrochloric acid at 100°C for up to 120 minutes of heating at atmospheric pressure. Phosphoric acid causes more rapid decomposition of DMSO than does sulfuric or hydrochloric acid. Detected decomposition products are dimethyl sulfide,...

Just like we learned about the Physical properties of potassium iodate previously, chemical properties of potassium iodate are explained below: When in the presence of strong acid like sulphuric acid, potassium iodate combines with potassium iodide, it produces potassium sulfate, iodine, and water. ...
Lab 4 Experiment 1: Physical and Chemical Properties. Physical and Chemical Changes. Below is the list of substances where you will be identifying physical properties and chemical properties. Substance (Formula) Sugar (C12H22O11) Salt (NaCl) Citric acid (C6H8O7) Unknown liquid (B): This is...
The stabilization efficiency was assessed by leaching tests in de-ionized water and hydrochloric acid (0.1 M, HCl). Then, the physical properties were determined to evaluate the impact of heavy metals on the structural performance of the binder. Results demonstrated that the prepared geopolym...
What are the physical properties of carbonate minerals? Recrystallization: Recrystallization is when a substance is dissolved so that it can be purified in a hot liquid. When the solvent cools down, the solution is saturated with the solute that crystalizes, or forms a solid again. Carbonate mine...
