A student titrates a solution of Al(OH)3 with
HCl. The student dispensed 12.00mL of
Al(OH)3 solution of unknown concentration and
titrated the sample to the end point. The titration required
15.00mL of 0.178M HCl to react the end point.
A HCl + B Al(OH)3 ---> C H2O + D
AlCl3
What is the concentration of the unknown
Al(OH)3solution in mol/L?
A student attempts to titrate 10.00mL of a 0.879M solution of
NaOH with 0.15M HCl. What volume of HCl in mL is required to reach
the end point?
Formula: C4H6ClBr
Draw 1 structure.
Assign the molecular geometry for each central atom
Draw 1 constitutional isomer for this formula
Draw 1 stereoisomer for this formula
6.Calculate the concentration of Cl- present in
a solution obtained by mixing 160.4mL of 0.25M HCl, 30.4mL of 0.13M
K2CO3, and 25.0 mL of 0.28M
CuCl3.
7. A student wants to complete neutralize a 5.00g sample of
K2CO3 with a stock solution of 0.15M
H3PO4.
Balance the following equation. Place a 1 if the coefficient is
1.
AK2CO3+ BH3PO4.
---> CK3PO4.
+ DCO2 + EH2O
8. A student wants to complete neutralize a 5.00g sample of
K2CO3 with a stock solution of 0.15M
H3PO4.
A K2CO3+ B H3PO4.
---> C K3PO4. + D CO2 + E
H2O
What volume of 0.15M
H3PO4 in
mL is required to completely react 5.00g of
K2CO3 ?
9. A student wants to determine the empirical formula of a
copper hydroxide salt via titration.
A student takes 25.0 mL of a 0.26 M solution of the Cu(OH)x salt
and titrates it with 0.213M HCl. The student found it required
91.5mL of 0.213M HCl to reach the end point.
What is the value of x in Cu(OH)x?
