Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'кислить' (to make sour in a broad sense); 'acidulate' is more precise and formal. Avoid direct translation as 'окислять', which is 'oxidise'.
Common Mistakes
- Using it to mean 'corrode' or 'dissolve'. Confusing it with 'acidify' (which can imply a stronger/more complete process).
