acids, bases and salts

excellent. Let us now look at some examples in the lab and in real life

Uhhhh I think so

Hey, you remember when Miss taked about neutralization reactions

Neutralization reactions are also exothermic which means they produce heat energy

That's when all the OH- ions in the alkali react with all the H+ from an acid

+ info

+ info

It can also be done by performing a thermometric titration

This can be done by performing a titration using an indicator

To determine neutralization point in an acid-base reaction

Also refer to page 78 Concise Chemistry by Anne Tindale

The components of toothpaste, the use of antacids and the use of lime (calcium oxide) in soil treatment

But what about neutralization reactions in real life

Let me think. I remember Miss talking about 3 things. I remember now

These treat indigestion, acid reflux and hearturn by neutralizing excess hydrochloric acid in the stomach.

Antacids

Lime is added to neutralize acidic soils.Lime + ammonium fertilizer simultaneously is not advised as the two react together releasing ammonia NH3 gas. Result=loss of beneficicial nitrogen to soil

Soil Treatment

+ info

+ info

+ info

Sodium hydrogencarbonate neutralizes any acid present.The fluoride ions react with a compound in the tooth enamel forming a new compound that does not react with acid. Both conditions above reduce tooth decay.

Toothpaste

neutralization reactions in everyday life

THANKS!
