Which of following acids forms normal salts only?
Tetraoxosulphate (VI) acid
Trioxosulphate (IV) acid
Acetic acid
Tetraoxophosphate (V) acid
Correct answer is C
So we can determine that the basicity of Acetic acid is 1 because it releases one hydrogen ion in an aqueous solution.
Due to this they act as very weak acids. When weak acid reacts with strong base, they tend to form normal salt.
The gas given off when NH4 Cl is heated with an alkali is
H2
Cl2
N2
NH3
Correct answer is D

123g
139g
155g
182g
Correct answer is D
S + O\(_2\) → SO\(_2\).
According to the equation 32g of O\(_2\) produced 64g of SO\(_2\)
therefore 91g of O2 will produce yg of SO2
y = \(\frac{91 * 64}{32}\)
y = 182g of SO\(_2\)
1.80g
3.55g
7.10g
15.50g
Correct answer is B
1 mole Cl\(_2\) occupy 22.4dm\(^3\)
i.e 2 x 35.5 → 22.4 ; x → 1. 12
:. x = \(\frac{1.12}{22.4}\) x 2 x 35.5 = 3.55
50cm3
150cm3
200cm3
300cm3
Correct answer is B
According to the equation 2NH3 → N3 + 3H2
2 x 22400cm3 of ammonia will produce
3 x 22400cm3 of hydrogen
If 100cm3 of NH3 is used.
:. H2 volume = \(\frac{100}{2x22400} x 3x22400
=150cm3
