What is Normality ? ( Chemistry Online Guru )

today we will discuss about concentration methods there are so many concentration methods today we will discuss about

normality

what

is

normality

normality is the number of gram equivalents of solute present in a liter of solution means the number of gram equivalents of solute divided by the volume of solution the volume of the solution is taken in liters we can calculate the number of equivalents in grams its formula is the weight of the solute divided by the equivalent weight normality is represented by n so its formula is n equal to W when seeing w is the weight of the solute in grams e is the equivalent weight v is the volume of solution in liters the unit of normality is the equivalent in grams per liter how can we calculate the equivalent weight equivalent weight of the acid the equivalent weight of the acid is calculated using the formula molecular weight of the acid divided by the basicity of the acid before calculating the equivalent? the weight of the acid it is necessary to know the basicity of the acid number of the replaceable H atom present in the acid is equal to the basicity of the acid, for example, CL its basicity is 1 because in HCl 1 replaceable H atoms present the basicity of the h2so4 is 2 because 2 duplicable H atoms are present in h2 so4 the basicity of orthophosphoric acid h3po4 is 3 because there are 3 replaceable h atoms now we calculate the equivalent weight of HCl its molecular weight is 1 plus 35 point 5 divided by the basicity that is 1 so the equivalent weight of HCl is 36.5 similarly we can calculate the equivalent weight of h2so4 its molecular weight is 2 over 1 plus 32 plus 16 over 4 divided by basically that is true so molecular we talk about h2so4 is 98 when divided by 2 we get 49 now

what

is the normal solution but?

Is it referred to as normal solution when one gram equivalent of solute is present in one liter of solution? So the solution is a normal solution. What do you mean by n times 10 solution when there is 1 equivalent to 10 grams in 1 liter of solution? So the solution is n. by solution 10 please share this video and for more details or more articles check
