If an acid base reaction produces a solution with a pH of 7 at its equivalence point, why does an indicator solution that changes color at either a pH of 5 of 9 work just as well as one that changes at a pH of 7
What is the strongest base that may exist in water? What happens to stronger bases? (Use methoxide, CH3O1-, as an example.)
What is the maximum mass, in gram, of Fe3O4, that can be produced from this reaction? B)If 3.26 g of Fe3O4 are actually made, what is the percent yield of this process
The total phosphate concentration is 0.001 M. No other weak acids or bases are present. How many millimeters of 0.5 M H2SO4 are needed to decrease the pH of 1 liter of this water to 6.0
Combine the above two equations with that for the formation of liquid water and use addition and/or subtraction(i.e. Hess's Law) to arrive at the equation for the formation of magnesium oxide.
Reaction/exchange rates of CO2 and O2 in the alveoli must be included. Given that the inhalation and exhalation times are different, calculate the rate of important gases during the inhalation and exhalation process.
Explain the structure of the main mononitration product(s) of 3 bromo 1 nitrobenzen?
Write an equation for the dissociation that occurs when NaCl is mixed with water. Calculate the effective molality for the NaCl mixture. 120 g of salt and 600 g of H2O
Aspirin has a pKa of 3.5 and is neutral in its protonated form (i.e. HA). Acetaminophen has a pKa of 9.5 and is also neutral in its protonated form. Predict the elution order of the two compounds in capillary electrophoresis.
If 22.15 mL of 0.100 M sulfuric acid is required to neutralize 10.0mL of lithium hydroxide solution, what is the molar concentration of the base. H2SO4(aq) + 2LiOH(aq) -right arrow Li2SO4(aq) + 2 H2O(I)
