A well-fermented brined cucumber finishes at a pH of roughly

  • A.Three point one to three point five
  • B.Six point five to seven point zero
  • C.Eight point five to nine point zero
  • D.Five point five to six point zero

Answer: A

The accumulated lactic acid, around 1.5 per cent, brings the brine to a pH near 3.1 to 3.5, which is low enough to prevent the growth of spoilage and pathogenic bacteria. A pickle that fails to reach this range is not safely preserved by acid alone.
