Description
Acids:
Acids are a class of substances characterized by their ability to donate protons (hydrogen ions, H+) to other substances. They are often defined as proton donors and typically have a sour taste. Acids can be categorized as strong or weak based on their ability to dissociate entirely or partially in an aqueous solution.
When an acid dissolves in water, it releases positively charged hydrogen ions (H+). In chemical reactions, these hydrogen ions can interact with other substances, such as bases or metals.
Common examples of acids include hydrochloric acid (HCl), sulphuric acid (H2SO4), nitric acid (HNO3), and acetic acid (CH3COOH). Acids play essential roles in various chemical processes, such as food digestion, industrial processes, and chemical reactions.
When an acid reacts with a metal, a salt and hydrogen gas are produced. This is a type of single displacement reaction where the metal displaces the hydrogen from the acid to form a salt.
In this specific activity, zinc granules are added to dilute sulphuric acid. The zinc displaces the hydrogen from the sulphuric acid to form zinc sulphate, a salt and hydrogen gas. The chemical equation for this reaction is as follows:
The hydrogen gas produced in this reaction is then tested by passing it through a soap solution to form bubbles. When a burning candle is brought near these bubbles, they burst with a ‘pop’ sound, confirming the presence of hydrogen gas.
Bases:
A base is a substance that can accept a proton (H+) or donate an electron pair in a chemical reaction. Bases are commonly characterized by their ability to neutralize acids, forming water and salt. They typically have a bitter taste and a slippery feel.
Bases are often classified into two categories based on their solubility in water:
- Strong Bases: These are highly soluble in water and completely dissociate to produce hydroxide ions (OH–) in the solution. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
- Weak Bases: These are partially soluble in water and do not completely dissociate. They produce fewer hydroxide ions in the solution. Ammonia (NH3) is a typical example of a weak base.
NaOH reacts with zinc to form sodium zincate and hydrogen.
