An 85.469 g sample of elderberries was blended with 100.0 mL of water to extract the Vitamin C. The solid material was filtered away from the aqueous layer. Using the iodometric method for Vitamin C discussed in the Fruit Analysis lab manual the resulting 100.0 mL solution was prepared for titration. A volume of 10.54 mL of 0.005384 M KIO3 to reach the end point. What is the amount, in mg, of Vitamin C found in 100.0 g of elderberries based upon this experimental result

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.
