(a). IF both (A) and (R) are correct and (R) is the correct explanation of (A). (b). If both (A) and (R) are correct but (R) is not the correct explanation of (A). (c). If (A) is correct, but (R) is incorrect. (d). If (A) is incorrect, but (R) is correct. (e) if both (A) and (R) are incorrect. Assertion (A): In the titration of Na_(2)CO_(3) with HCl using methyl orange indicator the volume required at the equivalence point is twice that of the acid required using phenolphthalein indicator. Reason (R): 2 " mol of "HCl are required for complete neutralization of one mole of Na_(2)CO_(3) .

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) .

How many moles of HCl will be required to completely convert 1 moles of borax into borax acid ?

A sample of NaHCO_(3) + Na_(2)CO_(3) required 20 ml of HCl using phenolphthalein as indicator and 35ml more required if methyl orange is used as indicator . Then molar ratio of NaHCO_(3) to Na_(2)CO_(3) is

Volume of 0.1M HCl required to react completely with 1g equimolar mixture of Na_(2)CO_(3) and NaHCO_(3) is

How many moles of KMnO_(4) are required to oxidise one mole of SnCl_(2) in acidic medium?

The overall equation for the reaction between sodium carbonate solution and dilute hydrochloric acid is Na_(2)CO_(3)(aq.)+2HCl(aq.)rarrNaCl(aq)+CO_(2)(g)H_(2)O(l) If you had the two solutions of the same concentration, you would have to use double volume of HCl to reach the equivalence point. Indicators change their colours at the end point of the reaction and hence we are able to know the end points (equivalence points of reactions). How many ml of 1N HCl are required for X milimoles of NaOH + Y milimoles of Na_(2)CO_(3)+Z milimoles of NaHCO_(3) with methyl orange indicator

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.
