Incorrect statement for the use of indicators in acid-base titration is :
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason RAssertion A: Hydrolysis of an alkyl chloride is a slow reaction but in the presence of NaI, the rate of the hydrolysis increasesReason R: $\,I ^{-}$is a good nucleophile as well as a good leaving groupIn the light of the above statements, choose the correct answer from the options given below
How many moles of Ba3(PO4)2 will be formed by the reaction of 5 moles of BaCl2 and 3 moles of Na3(PO4).
A binary compound has Y-atoms forming FCC unit cell and another type of X-atoms occupying \(\frac{1}{3}\)rd of tetrahedral voids. Find out the molecular formula of the compound
The value of \(log_{10}K\) for a reaction A ⇋ B is
(Given,
\(\Delta H^{\circ}_{298K}\) = –54.67 kJ \(mol^{-1}\)
\(\Delta H^{\circ}_{298K}\) = 10 kJ \(mol^{-1}\)
and R = 8.314 J \(K^{-1}mol^{-1}\)
2.303 × 8.314 × 298 = 5705)
