Chemistry Quiz On Acids And Bases!
Acids and bases affect chemistry and our day to day life as well. They can be identified by their taste; acids taste sour and bases taste bitter. Acids are found in many substances including food items but their presence in fruits is very prominent, e. G. , citric acid is present in citrus fruits such as orange and lemon. Vinegar contains acetic acid. Apart from these, some acids are widely used in the laboratory, like hydrochloric acid, sulfuric acid and nitric acid.
