Question

1.4 g of dolomite was dissolved (CaCO3 and MgCO3) was dissolved in 200 ml of 0.2 N HCl solution. After the reaction was complete , the resulting solution was diluted to 250 ml and 10 ml of this solution required 12 ml of 0.1 N NaOH solution for complete neutralization. Calculate the percentage of composition of the mixture

Answer 1

Answer:

i dont know the answer of the question

Answer 2

Answer:

something is wrong in your question

Explanation:

equivalent of 10ml is 1.2

equivalent of 250 = 30

equivalent of acid initial = 40

equivalent of acid reacted = 10

equivalent of caco3 + equivalent of mgco3 = 10

moles+moles=0.01

w/100 + 1.4-w/84 = 0.01

140-16w=84
