Milk souring is primarily caused by the activity of bacteria, specifically lactic acid bacteria, such as Lactobacillus. These bacteria ferment lactose, the sugar present in milk, into lactic acid. The increase in lactic acid lowers the pH of the milk, leading to the sour taste and curdling of the milk proteins. Additionally, other byproducts of bacterial metabolism, such as acetaldehyde and diacetyl, contribute to the characteristic flavor of sour milk. **

Yes, both the souring of milk and the melting of candle wax are chemical reactions. When milk sours, the bacteria in the milk produce lactic acid through a chemical reaction, causing the milk to sour. Similarly, when candle wax is heated, it undergoes a chemical reaction where the heat causes the wax molecules to break down and change from a solid to a liquid state, which is the process of melting. Therefore, both processes involve chemical reactions. **
