How many milliliters of 0.800 M KOH should be added to 5.02 g of 1,5-pentanedoic acid (C5H8O4, FM 132.11) to give a pH of 4.40 when diluted to 250 mL?
Now suppose, instead, that 47.318 g of avolatile soluteis dissolved in 480.0 g of water. This solute also does not react with water nor dissociate in solution.
Suppose a snack bar is burned in a calorimeter and heats 2,000 g water by 20 °C. How much heat energy was released? (Hint: Use the specific heat equation.) Give your answer in both joules and calories.
A common way of removing Cr3+ from solution is by precipitation of Cr(OH)3(s). An environmental engineer tells you that adjusting the pH to 8.5 will decrease total soluble Cr(III) to below 1 mg/L (1.92 x 10-5 M). Is this true?
One liter of water will dissolve 2.15* 10^-3 mol of PbF2 at 25 degrees c. Calculate the value of ksp for PbF2.
How many grams of dipotassium succinate trihydrate (K2C4H4O4·3H2O, MW = 248.32 g/mol) must be added to 500.0 mL of a 0.0319 M succinic acid solution to produce a pH of 5.808? Succinic acid has pKa values of 4.207 (pKa1) and 5.636 (pKa2)
Mehtanol-water solutions behave as essentially ideal solutions (the activity coefficients which measure deviation from ideality are equal to or close to one).
Hydrazine (N2H4) is a fuel used by some spacecraft. It is normally reacted with N2O4 according to the equation: N2H4(l) + N2O4 (g) 2 N2O(g) + 2 H2O (g) a) Identify the oxidizing agent and the reducing agent in the reaction
