  • What is the overall charge of an ionic compound?
    The overall charge of an ionic compound is zero; the positive and negative charges of the ions balance each other out.
  • What is the overall charge of the compound sodium chloride (NaCl)?
    The overall charge of sodium chloride (NaCl) is zero, as the Na+ and Cl- ions combine in a 1:1 ratio to form a neutral compound.
  • What is a spectator ion in the context of ionic salts?
    A spectator ion is an ion that does not participate in the chemical reaction and remains unchanged in solution.
  • Salts are always ________.
    Salts are always ionic compounds formed from the neutralization of acids and bases.
  • What is the minimum charge a transition metal cation must have to be considered acidic in a salt?
    A transition metal cation must have a charge of +2 or higher to be considered acidic in a salt.
  • How can you determine if a main group metal cation in a salt is acidic or neutral?
    A main group metal cation is acidic if it has a charge of +3 or higher; otherwise, it is neutral.
  • What is the rule for identifying whether an anion in a salt is basic or neutral?
    Add an H+ to the anion; if it forms a weak acid, the anion is basic, but if it forms a strong acid, the anion is neutral.
  • Why are group 1A and 2A metal cations always neutral in salts?
    Group 1A and 2A metals only form +1 and +2 cations, which do not meet the minimum charge requirement to be acidic, so they are always neutral.
  • What makes positively charged amines in salts automatically acidic?
    Positively charged amines, such as NH4+, are always acidic regardless of their structure or the accompanying anion.
