The titration of an acid (H2A) with LiOH solution generates the following titration curve. What are the main components (more th

an half of the initial amount of H2A, besides H2O) at equivalence point 1 (EP1) and equivalence point 2 (EP2)?
Main Components at EP1 Main Components at EP2
A H2A and OH− A2− and OH−
B HA− and Li+ A2− and Li+
C HA− and OH− HA− and Li+
D H2A and Li+ HA− and OH−

Answer:

B) HA⁻ and Li⁺ A²⁻ and Li⁺

Explanation:

Titration of acid H₂A with LiOH solution.

At first equivalent point

    H₂A + LiOH → HA⁻ + Li⁺ + H₂O

    Main component at (EP1) => HA⁻ and Li⁺

At second equivalence point

    HA⁻ + LiOH → A²⁻ + Li⁺ + H₂O

    Main component at (EP2) => A²⁻ and Li⁺

Therefore, the correct answer is B

Determine the molar mass of CuSO4×5H2O
asambeis [7]
248.72 g/mol

CuSO4 has a molar mass of 159.62. H2O has a molar mass of 18.02, which is multiplied by 5 to reflect the 5 H2O molecules.

159.62+5(18.02)=249.72 g/mol

Write a balanced chemical equation for the reaction of magnesium with hydrochloric acid (HCI (aq) to form Magnesium chloride and
ivann1987 [24]
Mg (s)       +    HCl (aq)    →  MgCl₂(s)   + H₂(g)

Looking at the equation :

We have 1 Mg at the left hand side and 1 Mg as well on the right hand side.
So that is balanced. 

We have 1 H at the left hand side and 2 H on the right hand side.
So that is not balanced.  Same for Chlorine. Cl.

We add 2 to the HCl on the left hand side and that balances it.

Mg(s)       +    2HCl(aq)    →  MgCl₂(s)  + H₂(g)
