What is the molarity of 40ml of NaOH if it takes 25ml of 0.5 molar HCl to neutralize it?

Oksanka [162]

Answer:

Molarity of 40 ml of NaoH is 0.3125 mL

Explanation:

As we know

Molarity of acid * volume of acid = molarity of base * volume of base

Substituting the given values, we get

$0.5 * 25 = X* 40 \\X = \frac{0.5*25}{40} \\X = 0.3125$

Molarity of 40 ml of NaoH is 0.3125 mL

What is the main factor responsible for the acidic and basic character of oxides?

lidiya [134]

Explanation:

<h3>We define non-metal oxide acidity in terms of the acidic solutions formed in reactions with water. For example, sulfur trioxide reacts with water to forms sulfuric acid. In sum, acidic oxides are oxides of non-metals, and basic oxides are oxides of metals. ... CrO is basic, Cr2O3 is amphoteric and CrO3 is acidic.</h3>
