The buret is filled with the NaOH titrant and the initial volume reading is immediately recorded without waiting the recommended 10-15 seconds. However, in part b-1, the 10-15 second time lapse does occur before the reading is made. Does this technique error result in an increase, a decrease, or have no effect on the reported perccent acetic acid in the vinegar?
Using a stock solution of 95.4ppm MgCO3, you are directed by your instructor to make calibration standards of 1.0, 7.5, and12.0 ppm. If you use 100mL volumetric flasks to make the solutions, what volume of stock solution will you require for each ..
what is the K value for compound Z in this biphasic system, (2) how much do you remove in each individual extraction, (3) how much of compound Z is extracted with those three 33.3 mL extractions added together, AND (4) how much is still in the wat..
Balance the following molecular equations for these reactions. Write the ionic equation for the reactions. Write the net ionic equation for the reactions.
Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
A sample of a gas occupies 1470 mL at 60.7?C and 740 torr. What volume would it occupy at the same pressure and 450?C.
125 mL of H_2O is initially at room temperature (22.0C). A chilled steel rod at 2.0C is placed in the water. If the final temperature of the system is 21.5C, what is the mass of the steel bar?
Complete this equation to show how hydrofluoric acid, HF, acts as a Brønsted-Lowry acid in water. HF+H2O=?
in order to make a solution that i s0.030 M in Cu SO4 what volume of the above solution should be diluted to 5.00 mL with water?
Suppose you wanted to make a pH=4.25buffer. What would be the best acid/base system: acetic acid/acetate or lactic acid/lactate? THe Ka of lactic acid is 8.32x10(exponent -4). Throughly explain your reasoning.
What volume of 3.50M H2S is required to react with excess O2 to produce enough NH3 to fill a cylinder that is 50ft long and has a diameter of 13 ft at a pressure of 450 torr and 20°F
The voltage across the leads of a glass pH-reference combination electrode immersed in a solution of pH 8.00 was 133 mV. Calculate the expected voltage if the pH of the solution is raised to 9.00
How long would it take for 1.50mol of water at 100.0 °C to be converted completely into steam if heat were added at a constant rate of 21.0 J/s?
