What number of liters of STP CO2 is produced when 7x10^23 molecules of O2 is consumed?
What number of molecules of CO2 will be produced if 3x10^24 molecules of O2(g) reacts?
What volume of Cl2(g) measured at STP is produced when 7.65 g of HCl(aq) reacts?
What is the relationship between equilibrium constants of acid-base, complexometric, precipitation, and redox titration and the feasibility of titration? What are the similarities and differences between the four types of titration? Are there other factors that need to be considered when assessing the feasibility of titration?
A 50.00 mL sample of a citrus drink consumed 14.33 mL of 0.05136 M KOH to reach the phenolphthalein end point. Express the sample’s acidity as grams of citric acid, HOC(CH2CO2H)2, per 100 mL. Note: phenolphthalein pH range = 8.3 – 10. pKa1 = 3.13, pKa2 = 4.76, pKa3 = 6.40.
