strength of a solution

Strength of a solution is defined as the amount of the solute in gms, present in one litre of the solution. It is expressed as gL - 1 . Mathematicall..

It is customary to indicate the strength of a sample of hydrogen peroxide solution in terms of the 'volume of oxygen at NTP that one volume of hydrogen peroxide gives on heating'. When the grade of H 2 O 2 in volumes is given, its percentage strength can be calculate..

How much pure alcohol should be added to 700 ml of a 16% solution to make its strength 80%? => 2240 ml or 350 ml or 224 ml or 700 ml..

In gaseous state, hydrogen halides are covalent. But in aqueous solutions, they ionize and behave as acids. The acidic strength of these acids decreases in the order: HI > HBr > HCI > HF Thus, HF is the weakest acid and HI is the strongest acid among these halogen hydrides. Exp..

2 M solution of H 2 O 2 means 2 mol of H 2 O 2 in one litre of the solution. Molar mass of H 2 O 2 = (2x1 + 2x16) g/mol =(2 + 32) g/mol = 34 g/mol Thus, there are 68 g (= 2 x 34 g) of H 2 O 2 in one litre of the solution. So, Mass of H 2 O 2 in 100 mL of sol..

[H 3 O + ] = 6.2 x 10 - 9 M pH = -log [H 3 O + ] pH = -log [6.2 x 10 - 9 ] = -(log 6.2 - 9 log 10) = -log 6.2 + 9 x 1 (log 6.2 = 0.79) = 9 - 0.79 = 8.21 8. Acid A, B, C and D have the following pKa values: A = 1.5, B = 3.5, C = 2.0, D = 5.0. Arrange these acids in..

The order of acid strength is reverse of what may normally be expected on the basis of electronegativity of halogens. Since F is most electronegative, BF 3 should be most electron deficient and thus should be strongest acid. The anomalous behavior is explained on the basis of tendency o..

We know that, pK a = -log K a or K a = 10 - p K a Therefore, for the given acids, K a (A) = 10 - 1 . 5 K a (B) = 10 - 3 . 5 K a (C) = 10 - 2 . 0 K a (D) = 10 - 5 . 0 Since, 10 - 5 . 0 < 10 - 3 . 5 < 10 - 2 . 0 < 10 - 1 . 5 He..

The strength of an acid depends on the concentration of the hydronium ions (H 3 O + ) present in a solution. We know that greater the number of hydronium ions present, greater is the strength of acid. However, some acids do not dissociate to any appreciable extent in ..

Strength of an acid depends on the concentration of hydronium ions present in a solution. Greater the numbers of hydronium ions present, greater is the strength of the aci..
