CHLORIDES ACROSS PERIOD 3
Chlorides Across Period 3 Quiz
Test your knowledge on the behavior of chlorides across Period 3 in the periodic table! This quiz delves into the chemistry of elements such as sodium, aluminum, and silicon, specifically focusing on their chlorides and reactions.
With challenging multiple-choice questions, you will explore topics such as oxidation states, hydration reactions, and properties of chlorides in solution.
On hydration, [Al(H20)5]3+(aq) produce
H2 (g) and [Al(H20)4]2+ (aq)
H2(g) and [Al(H20)4]+(aq)
All of above
H+ and [Al(H20)5]2+
Oxidation nimber Si in SiCl4 is
+2
+3
+4
+5
Solution is turned acidic upon hydration of AlCl3,because
Al3+ ions are formed
Cl- are formed
H+ are formed
All of above
In S2Cl2, the oxidation is
+1
+24
+3
+1000
Consider the reaction: SiCl2(l) + 2H20(l) ------> SiO2 + HCl
Pink precipitate
White precipitate
Blue precipitate
Rainbow precipitate
An element of the third period (Na to S) is heated in chlorine. The product is purified and then added to water. The resulting solution is found, What is the element?
Sodium
Aluminium
Silicon
Phosphorus
Which statement correctly describes what happens when silicon tetrachloride is added to water?
The SiCl4 dissolves to give a neutral solution only
The SiCl4 reacts to give an acidic solution only
The SiCl4 reacts to give a precipitate and an acidic solution
The SiCl4 reacts to give a precipitate and a neutral solution
Why is the ionic radius of a chloride ion larger than the the ionic radius of a sodium ion?
A chloride ion has one more occupied electron
Chlorine has a higher proton number than sodium
Ionic radius increases regularly across the third period
Sodium is a metal, chlorine is a non-metal
Which chloride of a period 3 element dissolves in water to form a solution with a pH of 7 ?
Aluminium chloride
Phosphorus (V) chloride
Silicon (IV) chloride
Sodium chloride
The oxide and chloride of an element X are separately mixed with water. The two resulting solutions have the same effect on litmus. What is the element X ?
Sodium
Magnesium
Aluminium
Phosphorus
