Assertion: In the titration of `Na_(2)CO_(3)` with `HCl` using methyl orange indicator, the volume of acid required is twice that of the acid required using phenolphthalein as indicaton. Reason: Two moles of `HCl` are required for the complete neutralisation of one mole of `Na_(2)CO_(3)`.
A
If both the statements are TRUE and STATEMENT-2 is the correct explation of STATEMENT-1
B
If both the statements are TRUE AND STATEMENT-2 is NOT the correct explanation of STATEMENT-1
Show that the time required for completion of 3/4th of a first order reaction ia twice the time required for the completion of 1/2 of the reaction.
Consider a titration of potassium dichromate solution with acidified Mohr’s salt solution using diphenylamine as indicator. The number of moles of Mohr’s salt required per mole of dichromate is
How many moles of methane are required to produce 22 g of CO2 for combustion?
How many moles of electrons are required to Produce 10.0 g of Al from molten Al_2O_3 ?
Complete and balance equation : Na2CO3 + HCl →
0.1g of a solution containing Na_2 CO_3 and NaHCO_3 requires 10mL of 0.01 N HCI for neutralization using phenolphthalein as an indicator. mass % of Na_2 CO_3 in solution is :
In the titration of Fe^(2+) ions with KMnO_4 in acidic medium, why is dilute H_2SO_4 used and not dilute HCl?
A mixture NaOH+Na_(2)CO_(3) required 25mL of 0.1 M HCl using using phenolpththalein indicator. However the same amount of the mixture required 30mL of 0.1M HCl when methyl orange was used as the indicator. The molar ration of NaOH and Na_(2)CO_(3) in the mixture was:
STATEMENT-1 : For the reaction in titration Na_(2)CO_(3)+HCL to NaCl+NaHCO_(3) , the suitable indicator is phennophthalein. STATEMENT-2 : Phenolphthalein provide its colour in acidic medium.
