Acids and Alkailis

What will a concentrated acid have more of

A concentrated acid will have more acid particles per litre than a dilute acid

What are some common lab acids

Sulfiroc acid H2SO4

Hydronic acid HLC

Nitric acid HNO3

What is an indicator

An indicator is a solution that changes colour to determine the PH of a solution

What are some common indicators

Universal indicator, it turns red in acidic solutions and blue in alkaline solutions

Blue litmus paper turns red in acids

Red litmus paper turns blue in alkaline solutions

What is a well known Alkali

Sodium hydroxide NaOH is a well known alkali

What is neutralisation

Neutralisation involves adding an alkali to an acid to produce a neutral solution

Name tow acids

lemon water, vinegar

Name three alkali

Toothpaste

milk

oven cleaner

Name one neutral solution

water

What does hydronic acid make

Hydronic acid makes chloride salts

What does sulfuric acid make

sulfuric acid makes sulfate salts

What does nitric acid make

Nitric acid makes nitrate salts

How do you make copper sulfate crystals

Add powdered copper oxide to sulfuric acid

Filter the mixture to collect the un-reacted copper oxide and collect the copper sulfate solution

Place the copper sulphate solution into an evaporating dish and heat gently

The water will evaporate and copper sulfate crystals will form in the evaporating dish

Why are neutralisation reactions useful

Neutralisation reactions are useful because they can be used to neutralise soil or lakes
