confidently and competently teach tricky aspects of acid and base chemistry to secondary school students; and access a range of activities and resources to support students and their learning about ...

This educational film explores acid-base indicators and their color changes in response to acidity. It demonstrates how ...

Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...

When an acid is neutralised, it forms a salt. Making salts Acids react with metals, bases and carbonates to produce salts. Neutralisation is the reaction between an acid and a base. Titration and ...

Neutralisation is the reaction of an acid with a base that results in the pH moving towards 7. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and ...

Pour desired household chemicals into separate 50 mL beakers. Add a few drops of universal indicator OR about 25 mL of red cabbage indicator and mix. Compare colors to standard solutions in lighted ...

When an acid like lemon juice gets in the water, a reaction makes the indicator molecule change shape and it looks pink. When instead a base gets in the water, a different reaction happens that ...

Previous studies have shown that organic chemistry in concentrated sulfuric acid is possible, and that nucleic acid bases – including adenosine, cytosine, guanine, thymine and uracil which form ...
