Interpretation: The titration curve for strong acid and strong base; The major species present before and after the reaction at various points in the curve; reaction that takes place in a strong
Concept introduction: The strong acid has a tendency to undergo complete dissociation. In the same way a strong base is the one that undergoes complete dissociation in aqueous solution.
To determine: The titration curve for strong acid and strong base; The major species present before and after the reaction at various points in the curve; reaction that takes place in a strong acid-strong base titration,

- someone else has already submitted the same question on here and it was the incorrect answer.arrow_forwardThe reaction: 2NO2(g) ⇌ N2O4(g) is an exothermic reaction, ΔH=-58.0 kJ/molrxn at 0°C the KP is 58.If the initial partial pressures of both NO2(g) and N2O4(g) are 2.00 atm:A) Is the reaction at equilibrium? If not, what is the value of Q? B) Which direction will the reaction go to reach equilibrium? C) Use an ICE table to find the equilibrium pressures.arrow_forwardThe dissociation of the weak acid, nitrous acid, HNO2, takes place according to the reaction: HNO2 (aq) ⇌ H+(aq) + NO2–(aq) K=7.2 X 10-4 When 1.00 mole of HNO2 is added to 1.00 L of water, the H+ concentration at equilibrium is 0.0265 M.A) Calculate the value of Q if 1.00 L of water is added? B) How will reaction shift if 1.00 L of water is added?arrow_forward
- Suppose a certain copolymer elastomeric material “styrene-butadiene rubber”) contains styrene ("S") monomers –(C8H8)– and butadiene ("B") monomers –(C4H6)– and that their numerical ratio S:B = 1:8. What is the mass ratio mS:mB of the two monomers in the material? What is the molecular mass M of a macromolecule of this copolymer with degree of polymerization n = 60,000?
