Question
Write the symbol .for titanium. What is the atomic number of it in the periodic table?? How many protons and electrons are there in the atom of titanium? Give the highest possible and lowest possible oxidation state for titanium. Determine its molar mass. 2. Na2TiO3. Determine the molar mass for this compound and the oxidation state of titanium in it: Write the oxide formula of titanium for the corresponding oxidation state. Determine whether this oxide will react with HCI, NaOH, and write the corresponding reaction equations. 3 Name these compounds: NaNO3, HNO3, K2SO3.Explanation / Answer
Symbol for titanium is Ti
Atomic number is 22
No. of electrons = No. of protons = 22
The configuration of valence electron is 3s2, 3p6 3d4. Therefore, lowest possible oxidation state is +1 (promoting one 3s electron to 3d to make it half full) and removing the other 3s electron
Highest possible oxidation state is +4 - removing all the 3d electrons.
Molar mass of Ti is 47.87 g/mol. The fraction in molar mass is due to the different mole fraction of Ti isotopes present in the naturally occuring Ti
2) Molar mass of Na2TiO3 is (2*23)+(47.87)+(3*16) = 141.87 g/mol.
Oxidation state of Ti in Na2TiO3 is = 0 - (2*1 + (-2*3) = 0 - 2 +6 = +4
The oxide of Ti with oxidation state +4 for Ti is TiO2
TiO2 does not react with HCl and it reacts with concentrated NaOH to form sodium titanate
TiO2 + 2NaOH -----> Na2TiO3 + H2O
NaNO3 - Sodium nitrate; HNO3 - Nitric acid; K2SO3 - Potassium sulfite
