What happens if lemon juice and sodium hydroxide?

When lemon juice, which is acidic due to citric acid, is mixed with sodium hydroxide (a strong base), a neutralization reaction occurs. The citric acid in the lemon juice reacts with sodium hydroxide to form sodium citrate and water, resulting in a solution that is less acidic. This reaction can produce heat and may alter the flavor profile of the lemon juice, making it taste less sour. If the amounts are carefully controlled, the resulting solution can be near neutral in pH.
