Orgosolver provides study tools to help students with their organic chemistry homework and preparation for quizzes, exams, or even the MCAT. Our tools, quizzes, and study guides are designed to help students test every reaction or mechanism with any molecule they draw!
Chemix is a free online editor for drawing lab diagrams. Simple and intuitive, it is designed for students and pupils to help them draw diagrams of common laboratory equipment and lab setup of science experiments.
24 Οκτ 2024 · Make sure the total number of electrons is the same on each side of the arrow. The carbon on the left has 3 bonds, so it has 6 electrons around it. 2 electrons from the lone pair on the bromide ion enter the scene, so there will be 8 electrons around the same carbon atom after the reaction.
There are several tests for sulfate ion to identify from other anions in qualitative analysis. Some of metal sulfate compounds are soluble in water and some metal sulfates form precipitates. Sulfate compounds of several d block metal cations form colours.
29 Αυγ 2023 · Most sulfates, including those of \(\ce{Na^{+}}\), \(\ce{K^{+}}\), and \(\ce{NH4^{+}}\), are soluble in water. Exceptions that are insoluble are white lead(II) sulfate and white barium sulfate: \[\ce{BaSO4(s) <=> Ba2+(aq) + SO42-(aq)} \nonumber \] with \(K_{sp} = 1.4 \times 10^{-8}\) \[\ce{PbSO4(s) <=> Pb2+(aq) + SO42-(aq)} \nonumber \]
