The reaction between titanium ( IV) oxide and bromine trifluoride to give liquid bromine , and oxygen is:
Thus from each three moles of titanium ( IV) oxide we will get three moles of oxygen molecule
The mass of oxygen obtained = 0.143g
The moles of oxygen obtained
=
So moles of titanium ( IV) oxide required will be 0.00447mol
the molar mass of titanium ( IV) oxide is 79.87g/mol
mass of titanium ( IV) oxide used will be =
This mass of titanium ( IV) oxide is present in 2.367g of impure sample
the mass percent will be
The percentage of titanium ( IV) oxide in impure sample is 15.08% (w/w)
Answer is (A)
Pottasium and Sodium salts are soluble in water. When these soaps are added to hard water. Hard water contains calcium or magnesium ions and they form Magnesium or Calcuim salts. These salts of magnesium and calcium precipitates out and are insoluble in water. This precipitation is called as dirt (the exact word for dirt is not acceptable here). This process is considered as the disadvantage of soap as well as using hard water.
