Chemistry
1 answer:
DochEvi [55]2 years ago
5 0

Explanation:

mole of acid/mole of base=(concentration of acid×volume of acid)/(concentration of base×volume of base)

Na/Nb=CaVa/CbVb

1/2=(Ca×16.7)/(0.2×25)

0.2×25=2×Ca×16.7

Ca=(0.2×25)/(2×16.7)

Ca=0.15mol/dm³

mole of acid=Concentration×volume

mole of acid=0.15×(16.7/1000)

mole of acid=2.5×10^-3moles

What is the [H ] of a solution of 0.001 M aqueous sulfuric acid (H2SO4) is H2SO4 ionizes in water according to the balanced chem
Ainat [17]

Answer:  0.002 M

Explanation:

The balanced chemical equation for ionization of H_2SO_4 in water is:

H_2SO_4\rightarrow 2H^++SO_4^{2-}

According to stoichiometry :

1 mole of H_2SO_4 ionizes to give =2 mole of H^+ ions

0.001 mole of H_2SO_4 ionizes to give = \frac{2}{1}\times 0.001=0.002 mole of H^+ ions

Thus H^+ of a solution of 0.001 M aqueous sulfuric acid is 0.002 M
