Hi,
Strong electrolytes fall into three categories: strong acids, strong bases, and soluble salts.
So, the option for the first question is b, NaCl and NH4Cl.
for second question,
Molecules are nonelectrolytes.
So, the option is both a and d. that is Sugar (C6H12O6) and Ethanol (C2H5OH).
All the best
Select the pair representing two strong electrolytes. CH_3COOH and HCl NaCl and NH_4Cl KOH and HF...
List of Electrolytes:
NaCl, H3PO4, HC2H3O2(also written as CH3COOH), H3BO3, C2H6O2,
CaCl2, CH3OH, HCl, and AlCl3, Tap Water and DI Water
3. a) What can be concluded about how your acids are classified (are they strong, weak, or non-electrolytes?) b) Write a balanced equation for the dissociation of each of the acids, as was done for the ionic compounds. Here assume complete dissociation, disregarding the conductivity data for now. (HINT: Remember polyatomic ions! There should not be more than two...
Identify whether the following compounds are a strong electrolyte, a weak electrolyte or a non-electrolyte. Hydrochloric acid Sodium iodide Sucrose Acetic acid Propanol Will mixing the following pairs of salts produce a precipitate? If so, what precipitate will form? KCl & Pb(NO3)2 NaOH & HBr NH4NO3 & NaSO4 CaCl2 & KOH LiNO3 & NaI A standard wine bottle has a volume of 750 mL. If wine has a volume percent of 11.0%, how many millilitres of ethanol (drinking alcohol) is...
Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
