What is the molarity of a nitric acid solution if 43.13 mL 0.1000 M KOH solution is needed to neutralize 30.00 mL of the acid so
Leno4ka [110]

Answer:

0.144M

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below:

HNO3 + KOH —> KNO3 + H20

From the equation,

nA = 1

nB = 1

From the question given, we obtained the following:

Ma =?

Va = 30.00mL

Mb = 0.1000M

Vb = 43.13 mL

MaVa / MbVb = nA/nB

Ma x 30 / 0.1 x 43.13 = 1

Cross multiply to express in linear form

Ma x 30 = 0.1 x 43.13

Divide both side by 30

Ma = (0.1 x 43.13) /30 = 0.144M

The molarity of the nitric acid is 0.144M

Water combines with carbon dioxide Choose one: A. only in the atmosphere. B. to produce hydrogen sulfide. C. to precipitate calc
katovenus [111]

Water combines with carbon dioxide to produce slightly acidic groundwater

that dissolves limestone and forms caves.

This is because the reaction between water and carbondioxide to form

bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen

atoms thereby increasing the acidity.

The acidic environment results in the formation of acidic groundwater that

dissolves limestone and forms caves.
