percentage strength of a solution

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..

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..

The strength of an acid depends on the concentration of the hydronium ions present in a solution. Greater the number of hydronium ions present, greater is the strength of acid. However, some acids do not dissociate to any appreciable extent in water such as carbonic ac..

This unit is used in case of a liquid dissolved in another liquid. The volume percentage is defined as the volume of the solute per 100 parts by volume of solution. For e.g., If V A is the volume of component A present is V s o l volume of the solution. ..

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..

So if we calculate the volume of O 2 , which is liberated by 30.36 g of H 2 O 2 at NTP, this will correspond to volume strength of H 2 O 2 . As per the equation: 2 x 34 = 68 g of H 2 O 2 will liberate 22.4 L of O 2 at NTP 68 g of H 2 O 2 will produce O 2 at NTP = 22.4 L The give..

[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..

As per the equation, 2 {39 + 14 + (16 x 3)} (16 x 2) 2 (53 + 48) 32 2 (101) 32 202 32 Mass of oxygen liberated when 202 g of KNO 3 is heated = 32 g Percentage loss of mass = 15...
