When milk becomes too acidic, like when we add lemon juice or when it goes sour, the negative charge on the casein groupings becomes neutralized. On the other hand, if you add lemon juice or other acid to hot milk, the curdling happens much faster. You can see this if you make ricotta or soft paneer cheese at home!Click to see full answer. Simply so, what happens when you mix milk with lemon juice?The reaction of milk to lemon juice depends on the temperature of the milk. If the milk is hot, adding lemon juice causes the milk to curdle almost immediately. If the milk is cold when the lemon juice is added, the chemical reaction does not happen for some time.Also, why does milk curdle when you add lemon juice? When lemon juice is added, it increases milk’s acidity because lemon contains citric acid. When milk becomes acidic, the negative charge which keeps the casein separate is neutralized. Because of the lowering of pH, the calcium causes precipitation of casein and milk gets curdled. Similarly, it is asked, is mixing lemon juice with milk a physical or chemical change? A precipitate (pree SIP uh tayt) is a solid that forms from liquids during a chemical reaction. For instance, if you mix milk and lemon juice, the milk will curdle and form solids. Boiling is a physical change that changes a substance from a liquid to a gas.How do you add lemon juice to milk without curdling?You need to raise the pH of the juice(s) so that they are more nearly neutral before you add them to the milk. Milk curdles around pH of 4.6. As Dave Duffy suggested, you can add baking soda to the juice to do this.
