The government requires that the vinegar content be at least 4.00 (% m/v). The graph shows Gram values versus NaOH volume from a commercial vinegar titration. The concentration of the NaOH solution used was 0.111 mol/L and the volume of the vinegar sample equal to 3.10 mL. What is the concentration (%m/v) of acetic acid in the vinegar sample? Show the calculations. .
Which of the following statement/s is/are TRUE? When electricity is passed through a solution containing ions, 1) migration of the ions in the solutions, and 2) reactions of these ions at the electrode occur. The positively charged ions migrate toward the positive electrode (anode). When the ions have reached their respective electrodes, a reaction takes place wherein electrons are lost or gained. The amount of substance formed at the electrodes is proportional to the quantity of electricity passed. I, III, IV I, II, IV II, III, IV I, II, III
Marble, a material used in buildings and statues, has the chemical composition CaCO₃. CaCO₃ reacts with acid (H₃O⁺), dissolving the solid through the reaction: CaCO₃(s) + 2H₃O⁺(aq) → Ca²⁺(aq) + CO₂(g) + 3 H₂O(l) In 1985, rain water in central Pennsylvania had an approximate H₃O⁺ concentration of 8.0 × 10⁻² mM. What volume of rain would be needed to dissolve a small statue made of 4.50 kg of marble?

Iron(II) sulfate, is typically the source of iron in tablets prescribed to anemic patients, a condition where a person lacks enough healthy red blood cells. The tablets can be dissolved in dilute sulfuric acid to dissolve the Fe2+ ions. To determine the percentage by mass of iron within the tablets, the Fe2+ ions can be oxidised to Fe3+ using potassium permanganate, where MnO4− is reduced to Mn2+. Calculate the percentage by mass of iron in a 500 mg tablet that requires 24.53 cm3 of 0.0100 mol dm−3 KMnO4 to titrate the iron sample. State your answer to 3 significant figures. M(Fe) = 55.85 g mol−1
