The image above shows what happens when hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed with water. Which statement below is true about both solutions? A. Both solutions contain solutes that do not dissolve completely in water.

B. Both solutions are saturated because they contain the maximum concentration of a solute dissolved in the solvent.

C. Both solutions will conduct an electric current because they both contain ions that can carry a charge.

D. Both solutions are acidic because they both contain hydrogen.

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.
