Neutralization reaction is one type chemical of reaction in which acid and base reacts with each other in a quantitative amount to form salt and water. For example, if the initial HC2H3O2 had a concentration of 0.3 moles per liter, then the equilibrium concentration of HC2H3O2 is 0.3 moles per liter minus x. For example, acetic acid will react with magnesium (Mg) to form magnesium acetate (Mg(CH3COOH)2) and hydrogen gas (H2). Are you talking about elemental potassium, then I agree not much of acid base properties - strung reducing agent though. Then allow the liquid to drain from the pipette. Acetic Acid + Portlandite = Calcium Acetate + Water. As the titration is performed, the following data will be collected: Using this data, the molarity and mass percent of acetic acid in vinegar can be determined by performing a series of solution stoichiometry calculations (see Calculations Section). In small doses and dilute concentrations, the ingestion of acetic acid is harmless and potentially beneficial to humans. Replace immutable groups in compounds to avoid ambiguity. First, rinse the inside of the volumetric pipette with distilled water. \\ NaCH_3COO(aq) + HI(aq) \to NaI(aq) + CH_3COOH(aq), Write the net ionic equation for the following molecular equation. 50-mL burette*, 5-mL volumetric pipette*, pipette bulb*, ~ 0.1 M \(\ce{NaOH}\) (aq), vinegar, phenolphthalein, burette stand, two 250-mL (or 125 mL) Erlenmeyer flasks, wash bottle with distilled water, funnel.
