aggressive strength solution for size and strength

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..

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..

A chemical laboratory has 500 ml of 50% acid solution. How much water should be added so that the strength of the solution is 30%? => 33.33 ml or 250 ml or 183.33 ml or 333.33 ml..

The non-reactivity or inertness of nitrogen is due to: Its small atomic size. Its high bond order. The N-N bond in the N 2 molecule has a formal triple bond character The N N bond distance is 109.8 pm and is very stable. Its bond dissociation energy is 946kJ mol - 1 . The dissociat..

[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 ..
