Question

Please help me it’s due tmrw

1. In this section, you read about firefighters cleaning
up a hazardous spill of a base. This is the chemical
reaction they used:
H3PO4 + 3 KOH → K3PO4 + 3 H2O

(a) What type of reaction is this?

(b) Write the general equation for this kind of
reaction. Compare the equation above with the
general equation.

(c) Name the reactants

D) Name the products

Answer 1

a. double replacement

b. AB + CD ⇒ AD +CB

c and d

H₃PO₄ : Phosphoric acid

KOH : Potassium hydroxide

K₃PO₄ : Tripotassium phosphate

H₂O : water

Further explanation

Given

Reaction

H₃PO₄ + 3 KOH → K₃PO₄ + 3 H₂O

Required

Type of reaction

General equation

Name of reactants and product

Solution

• Type of reaction :

Double replacement reaction : Cations and anions of different compounds switch places

It can also be said as a neutralization reaction because it produces water(reaction between an acid and a base)

• General equation :

AB + CD ⇒ AD +CB

• Name of reactants and products

H₃PO₄ : Phosphoric acid

KOH : Potassium hydroxide

K₃PO₄ : Tripotassium phosphate

H₂O : water
