Titrate 100.0 ml of 0.10M Fe2+ solution with 0.10M Ce4+ solution. Calculate the potential of the solution when 90.0 ml of Ce4+ is added. Knowing E0(Fe3+/Fe2+) = 0.77V ; Knowing E0(Ce4+/Ce3+) = 1.45V. a.
0.57V

b.
0.67V

c.
0.83V

d.
0.71V

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.

idk what the question is about

50.23 i believe is correct but don't quote me on that.
