Concept explainers
(a)
Interpretation:
Whether sodium permanganate is a strong, weak or non-electrolyte is to be determined.
Concept introduction:
The electrolyte is the substance that produces ions when it is dissolved in a polar solvent. It breaks into positively and negatively charged ions that spread uniformly through the solvent. The electrolytic solution, as a whole, is electrically neutral. Sodium chloride, potassium chloride, calcium phosphate are some of the examples of electrolytes.
Strong electrolytes are those electrolytes that completely dissociates into its ions. These have a very high value of electrical conductance. Sodium chloride and potassium chloride are strong electrolytes.
Weak electrolytes are those electrolytes that partially dissociates into its ions. They are poor conductors of electricity. Acetic acid and carbonic acid are weak electrolytes.
Non-electrolytes are the substances that don’t dissociate into ions when they are dissolved in any solvent. They don’t conduct electricity. Urea, benzene, chloroform are non-electrolytes.

ALEKS 360 for Silberberg Chemistry: The Molecular Nature of Matter and Change
- I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."arrow_forwardSolve the spectroarrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward
