A student titrated 50 cm of sulphuric acid (H2SO4)of an unknown concentration

1 answer:

3 0

No. of mol. of NaOH used: (30/1000)*0.5= 0.015mol
Mole ratio of NaOH:H2SO4= 2:1
No. of mol. of H2SO4: 0.015/2= 0.0075mol
Conc. of acid= 0.0075/(50/1000)= 0.15moldm^-3

Hope it helps, drop a thanks

Which solution will form a precipitate when mixed with a solution of aqueous na2co3? which solution will form a precipitate when

trapecia [35]

Answer:

$CuCl_{2}(aq.)$ will form a precipitate of insoluble $CuCO_{3}$ when aqueous $Na_{2}CO_{3}$ is added.

Explanation:

According to solubility rule-

all carbonates are insoluble except group IA compounds and $NH_{4}^{+}$

all salts of sodium are soluble

When $Na_{2}CO_{3}$ is added to given solutions, a double displacement reaction takes place in each solution to form a sodium salt and a carbonate salt.

So, in accordance with solubility rule, addition of $Na_{2}CO_{3}$ into $CuCl_{2}(aq.)$ will result precipitation of insoluble $CuCO_{3}$

Reaction: $Na_{2}CO_{3}(aq.)+CuCl_{2}(aq.)\rightarrow 2NaCl(aq.)+CuCO_{3}(aq.)$
