The P/H Scale. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. If a pH is lower than 7 it indicates the solution is an acid. If it is above 7 it is a base or Alkaline. If a pH is a 7 it is neutral. Strong acids have lower pHs than weak acids and strong bases have lower pHs than weak bases.
The pH scale was developed to measure how acidic or basic a substance is. This scale measures pH from 0-14. Acids have pH values between 0 and 7 and bases have pH values between 7 and 14. Pure water is neutral and has a pH of exactly 7. Indicators are used to measure the pH of a substance. Often times, plant extracts will change color if exposed to acidic or basic conditions and can therefore be used to indicate if a substance is an acid or a base. Todayâs experiment focuses on the use of litmus paper, a most basic pH paper dating back many years.
