Last Answer : Answer : C
Description : In a solution containing phosphate buffer, the pH will be 7.4, if the ratio of monohydrogen phosphate : dihydrogen phosphate is (A) 4 : 1 (B) 5 : 1 (C) 10 : 1 (D) 20 : 1
Last Answer : Answer : A
Description : Important buffer system of extracellular fluid is (A) Bicarbonate/carbonic acid (B) Disodium hydrogen phosphate/sodium dihydrogen phosphate (C) Plasma proteins (D) Organic Phosphate
Description : An acid having basicity one is - (1) Sodium dihydrogen phosphate (2) Disodium hydrogen phosphate (3) Sodium phosphate (4) Phosphoric acid
Last Answer : (2) Disodium hydrogen phosphate Explanation: The basicity of an acid is the number of hydrogen ions (H+) which can be produced by the ionization of one molecule of the acid in aqueous solution. ... Similarly, the basicity of Disodium phosphate (Na2HPO4) is one since it has one H+ displaceable ion.
Description : What happens when alkali metals react with dihydrogen?
Last Answer : The alkali metals react with dihydrogen at about 673K (lithium at 1073K) to form hydrides. All the alkali metal hydrides are ionic solids with high melting points.
Description : An acid having basicity one is (1) Sodium dihydrogen phosphate (2) Disodium hydrogen phosphate (3) Sodium phosphate (4) Phosphoric acid
Last Answer : Disodium hydrogen phosphate
