Chapter 4: Q4.2 (page 180)

Question: State a general equation for a neutralization reaction.

Short Answer

Expert verified

Answer

When acid reacts with base, if forms salt and water and undergoes neutralization reaction. The general neutralization reaction is given below.

$A c i d + B a s e \to S a l t + W a t e r$

Step by step solution

01

Define neutralization reaction

A neutralization reaction is generally a reaction between an acid and a base which form salt as a product and water as a by-product.

The pH of a reaction between a strong base and strong acid is 7.

02

Write the general equation for neutralization reaction

The general neutralization reaction is:

$A c i d + B a s e \to S a l t + W a t e r$

If HA is acid and BOH is a base, the general acid-base reaction is given below.

data-custom-editor="chemistry" $HA + BOH \to HB + H_{2} O acid base salt water$

Example: Reaction of HCl with NaOH, forms salt and water.

data-custom-editor="chemistry" $HCI + NaOH \to NaCI + H_{2} O acid base salt water$

Explain why an oxidizing agent undergoes reduction.

The precipitation reaction between 25.0 mL of a solution containing a cation (purple) and 35.0 mL of a solution containing an anion (green) is depicted below (with ions shown as spheres and solvent molecules omitted for clarity).

(a) Given the following choices of reactants, write balanced total ionic and net ionic equations that best represent the reaction:

(1) KNO₃(aq) + CuCl₂(aq)

(2) NaClO₄(aq) + CaCl₂(aq)

(3) Li2SO₄(aq) + AgNO₃(aq)

(4) NH₄Br(aq) + Pb (CH₃COO)₂(aq)

(b) If each sphere represents 2.5 x 10^-3 mol of ion, find the total number of ions present.

(c) What is the mass of solid formed?

For the following aqueous reactions, complete and balance the molecular equation and write a net ionic equation:

(a) Manganese(II) sulfide + hydrobromic acid

(b) Potassium carbonate + strontium nitrate

(c) Potassium nitrite + hydrochloric acid

(d) Calcium hydroxide + nitric acid

(e) Barium acetate + iron(II) sulfate

(f) Zinc carbonate + sulfuric acid

(g) Copper(II) nitrate + hydrosulfuric acid

(h) Magnesium hydroxide + chloric acid

(i) Potassium chloride + ammonium phosphate

(j) Barium hydroxide + hydrocyanic acid

Is the total ionic equation the same as the net ionic equation when $S r {(OH)}_{2} (aq)$ and $H_{2} S O_{4} (aq)$ react? Explain.

One of the first steps in the enrichment of uranium for use in nuclear power plants involves a displacement reaction between ${UO}_{2} ?$ and aqueous HF:

${UO}_{2} (s) + HF (aq) \to {UF}_{4} (s) + H_{2} O (l) (unbalanced)$

How many liters of 2.40 M HF will react with 2.15 kg of ${UO}_{2} ?$
