If it requires 30.0 milliliters of 1.2 molar hcl to neutralize 20.0 milliliters of naoh, what is the concentration of the naoh solution? balanced equation: naoh hcl nacl h2o 0.60 m naoh 0.80 m naoh 1.3 m naoh 1.8 m naoh

The correct answer is 1.8 M NaOH.

Explanation:

The balanced chemical reaction for the neutralization of NaOH with HCl follows:

To calculate the molarity of the NaOH for neutralization, we use the equation:

where,

are the molarity and volume of HCl.

are the molarity and volume of NaOH.

We are given:

Putting values in above equation, we get:

Hence, the correct answer is 1.8 M NaOH.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

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.
