0.22 l of hno3 is titrated to equivalence using 0.10 l of 0.1 mnaoh. what is the concentration of the hno3? express the concentration of hno3 in molarity.

- Molarity of the acid solution is 0.045M.

Solution:- The balanced equation for the reaction of given acid and base is:

From the balanced equation, they react in 1:1 mol ratio. So, we could easily solve the problem using the equation:

where, is the molarity of acid, is the molarity of base, is the volume of acid and is the volume of base.

Let's plug in the given values in the equation:

on rearranging the above equation:

= 0.045M

So, the molarity of the acid solution is 0.045M.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
