5.00 mL of a 0.650 M solution of oxalic acid are dilute to 25.00 mL. If 27.11 mL of a NaOH solution are required to neutralize this diluted oxalic acid, what is the concentration of the NaOH in molarity terms?
Can someone show me step by step how to do this?
A laboratory procedure calls for making 570.0mL of a 1.6M KNO3 solution. How much KNO3 in grams is needed
dissolved in enough water to produce 162.5 mL of solution and that 18.8 mL of this solution is titrated to the stoichiometric point with 14.6 mL of 0.0307 M HCl(aq). What is the percentage purity of the original sample?
Calculate the pH of a solution made by adding 51 g of sodium acetate, NaCH3COO, to 18 g of acetic acid, CH3COOH, and dissolving in water to make 700. mL of solution. Hint given in feedback.
Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood.
Air is mostly nitrogen and oxygen. Determine the rms speed of nitrogen and oxygen at room temperature (20° C).
if 1.500 g of solute that has a molar mass of 125.0 g were dissolved in 35.00 g of camphor, what would be the resulting freezing point of the solution?
Determine the V of a voltaic cell (E°cell) if it is required to do 5.43 × 10¯3 Kilo Joule of work when a charge of 2.50 C is transmitted.
Find the concentration of Ca2+ and IO-3 in a saturated Ca(IO3)2 solution prepared by adding Ca(IO3)2 to a 0.015 M solution of KIO3
Naphthalene has a relatively high vapor pressure for a solid (because of its volatility, naphthalene is the active ingredient in some brands of mothballs). In view of this, what might happen if you place naphthalene under vacuum or in an oven for ..
Water at 0 degrees C was placed inside a vessel maintained at low pressure by a vacuum pump. After some of the water evaporated, the remainder froze. If 1.2g of water evaporated, how much ice was obtained? Use the heats of vaporization and fusion ..
