A mixture of magnesium carbonate and barium carbonate with a
total mass of 1.000 g was treated with excess of hydrochloric acid
to produce 0.407 g of carbon dioxide gas. Write balanced reaction
equations occurring to this system. Calculate the mass percent of
magnesium carbonate in the starting mixture (with three significant
figures).
What is the concentration of barium ions in a saturated solution
of barium sulfate?
Ksp(BaSO4) = (2.389x10^-8)
(Please explain in detail where numbers are coming from and
write clearly, if hand written) Thank you
A sample of hydrated barium chloride (BaCl2) has a mass of 8.26
g. After dehydration, the anhydrous sample has a mass of 7.04 g.
What is the correct name for the hydrate
A 200 mL saturadted solution of barium nitrate was obtaied by
dissolving 5.50 g of salt water.
a) determine the molar solubility of barium nitrate,
b) Calculate the solubility product constant of barium
nitrate,
c) determine of precipitate will form after addition of 0.011
mol of barium sulfate to the solution without a chnage in
volume.
A student is asked to standardize a solution of barium
hydroxide. He weighs out 1.06 g potassium hydrogen phthalate
(KHC8H4O4, treat this as a monoprotic acid). It requires 23.0 mL of
barium hydroxide to reach the endpoint. A. What is the molarity of
the barium hydroxide solution? =M
This barium hydroxide solution is then used to titrate an
unknown solution of hydrochloric acid. B. If 20.7 mL of the barium
hydroxide solution is required to neutralize 12.8 mL of
hydrochloric...
A student is asked to standardize a solution of barium
hydroxide. He weighs out 0.989 g potassium hydrogen phthalate
(KHC8H4O4, treat this as a monoprotic acid). It requires 25.0 mL of
barium hydroxide to reach the endpoint.
A. What is the molarity of the barium hydroxide solution?
This barium hydroxide solution is then used to titrate an
unknown solution of hydroiodic acid.
B. If 18.0 mL of the barium hydroxide solution is required to
neutralize 23.6 mL of hydroiodic acid,...
1) What mass (in g) of NH3must be dissolved in 475 g of methanol to make a 0.250 m solution?2) How many moles of KF are contained in
244 mL of 0.135 m KF solution? The density of the
solution is 1.22 g/mL3) Commercial grade HCl solutions are
typically 39.0% (by mass) HCl in water. Determine the
molarity of the HCl, if the solution has a density of 1.20
g/mL.4) A solution is prepared by dissolving
49.3 g of KBr in enough water to form 473 mL...
