12 Questions
Water is a toxic solvent widely used for chemical analyses.
False
Electrolytes form ions when dissolved in water, resulting in non-conductive solutions.
False
Ethanol is an example of a non-electrolyte.
True
According to Arrhenius theory, acids are sources of hydroxide ions (OH-).
False
Acetate ion is the conjugate base of acetic acid.
True
Water can act as both an acid and a base depending on the solute present.
True
Autoprotolysis is a spontaneous reaction that involves the formation of a pair of ionic species.
True
Chemical equilibrium is a state where the ratio of concentrations of reactants and products can vary over time.
False
The concentration of water in dilute aqueous solutions is usually higher than the concentration of hydronium and hydroxide ions.
False
The ion-product constant for water (Kw) at room temperature is typically 1.00×10^14.
True
Taking the negative logarithm of the ion-product constant for water provides an unhelpful relationship.
False
The ion-product constant for water allows for easy determination of the concentrations of hydronium and hydroxide ions in solutions.
True
