Important Questions on Acids, Bases and Salts
Read the following passage and answer the following questions.
Examples of Acids and Bases in Engineering
Removing corrosion: Engineers use strong acids to remove rust and other corrosive materials from metals through a process called pickling.
Batteries: Engineers design all kinds of batteries, such as car batteries, that include acids.
A typical car battery is made of plates of lead and lead dioxide submerged in an acidic solution. A chemical reaction releases electron to create the electricity used to start a car.
Fertilisers: Chemical engineers combine acids and bases to create useful products, such as chemical fertilisers for agriculture. To make a fertiliser, nitric acid, an acid, is combined with ammonia, a base, to produce ammonium nitrate.
Cleaners: Common household cleaners, such as ammonia, baking soda and bleach, are all bases.
Food preservation: Acids are common food preservatives. On food labels, ingredients such as phosphoric acid, citric acid, tartaric acid, malic acid, fumaric acid, lactic acid and vinegar serve as preservatives.
