Look at the products of the chemical reaction to determine if the reactant added to water caused an acid reaction, a base reaction, or a neutralization reaction.


Acid


Neutralization


Base

1.
2HF + 2CaOH -> 2H2O + 2NaF

2.
3HI + 2H2O -> 2H3O+ + 3I- + H+

3.
2CH3COO- + H2O -> CH3COO- + OH- + CH3COOH

0.05 moles of HCL are added to 2 L of H2O. What is the molarity of the solution?

Respuesta :

1. The reaction is a neutralization reaction

2. The reactant added to the water causes an acid reaction

3. The reactant added to the water causes a base reaction

4. The molarity of the solution is 0.025 M

What is a neutralization reaction?

This is a reaction involving an acid and a base which result in the formation of salt and water only

HF + NaOH –> H₂O + NaF

The reaction above indicates neutralization since the reaction produces water (H₂O) and salt (NaF) only

What is an acid?

An acid is a substance which dissolves in water to produce hydronium ion H₃O⁺

3HI + 2H₂O —> 2H₃O⁺ + 3I¯ + H⁺

The reaction above is an acid reaction since it produces H₃O⁺

What is a base?

A base is a substance which dissolves in water to produce hydroxide ion OH¯

2CH₃COO¯ + H₂O —> CH₃COO¯ + OH¯ + CH₃COOH

The reaction above is a base reaction since OH¯ is produced.

How to determine the molarity

  • Mole = 0.05 mole
  • Volume = 2 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 0.05 / 2

Molarity = 0.025 M
