Web-ate depends on the central atom, it's generally the most common n eg phosphate is PO4 3-, sulfate is SO4 2- but nitrate is NO3 - and chlorate is ClO3 - -ite is 1 less oxygen than -ate, phosphite is PO3 3-, sulfite is SO3 2-, nitrite is NO2 - Hypo- -ite means 1 oxygen less than -ite eg ClO2- is chlorite and ClO- is hypochlorite WebThe oxide of nitrogen formed when copper reacts with nitric acid depends upon the concentration and the temperature of the acid. The reaction of copper with cold, dilute acid produces NO as indicated by the following equation. 3Cu + 8H+ + 2NO3- → 3Cu2+ + 4H2O + 2NO In warm, concentrated acid, NO2 is formed.

WebMolecules such as N2 and ions such as Na+ and [Fe(CN)6]4− that contain no unpaired electrons are diamagnetic. Diamagnetic substances have a slight tendency to be repelled by magnetic fields. When an electron in an atom or ion is unpaired, the magnetic moment due to its spin makes the entire atom or ion paramagnetic. WebCu 2+ ions with CO 3 2− ions in an alkali medium form Cu 2 CO 3 (OH) 2, a broad and strong absorbent in the UV region, and intersect with the excitation spectra of the DPA-capped LaF 3:Eu 3+ NCs. More than 90% of the emission intensity of Eu 3+ ions was quenched after the addition of a 100 μM concentration of Cu 2+ ions. chrysomallos horn
