A simple way to estimate whether a molecule is a strong electrolyte, a weak electrolyte, or a nonelectrolyte is to examine an equation that accurately describes its behavior in water. When examining the chemical equations, start by looking at the direction and type of reaction arrow. A chemical equation reported in the literature may include a forward reaction arrow (→), equilibrium reaction arrow (=), or reverse reaction arrow (). Next, determine whether ions are likely to be present and, present, in what quantities they should be present. Predict whether each of the compounds depicted as reactants in the following equations would behave as a strong electrolyte, weak electrolyte, or nonelectrolyte. Assume you have no access to any other information and classify them only according to what the equation indicates. Drag the appropriate chemical equations to their respective bins. ► View Available Hint(s) 2C6H12O6 (aq) → C12H22O11 (aq) + H₂O(1) Nonelectrolyte HBr(aq) → H+(aq) + Br (aq) 2H₂O₂(aq) →2H₂O(1) + O₂(g) KCl(s) → K+ (aq) + Cl¯(aq) Weak electrolyte CH3NH₂ (aq)+ H₂O(1) = CH3NH3+ (aq) + OH-(aq) HNO₂ (aq) = H+(aq) + NO₂ (aq) Ca3(PO4) 2 (S) = 3Ca²+(aq) + 2PO4³-(aq) KOH(s) → K+ (aq) + OH-(aq) Reset Help Strong electrolyte

Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
Question
Transcribed Image Text:Part A
A simple way to estimate whether a molecule is a strong electrolyte, a weak electrolyte, or a nonelectrolyte is to examine an equation that accurately describes its behavior in water. When examining the
chemical equations, start by looking at the direction and type of reaction arrow. A chemical equation reported in the literature may include a forward reaction arrow (→), equilibrium reaction arrow (→), or
reverse reaction arrow (←). Next, determine whether ions are likely to be present and, if present, in what quantities they should be present.
Predict whether each of the compounds depicted as reactants in the following equations would behave as a strong electrolyte, weak electrolyte, or nonelectrolyte. Assume you have no access to any other
information and classify them only according to what the equation indicates.
