Litmus Test

A litmus test is a quick way to determine whether a substance is an <a href="https://www.wikiwhat.page/kavramlar/acid">acid</a> or a <a href="https://www.wikiwhat.page/kavramlar/base">base</a>. It uses a paper that has been treated with a natural dye obtained from <a href="https://www.wikiwhat.page/kavramlar/lichens">lichens</a>.

Here's what you need to know:

• How it works: The dye in litmus paper changes color depending on the <a href="https://www.wikiwhat.page/kavramlar/pH">pH</a> of the substance.
• Colors:
  • Acid: <a href="https://www.wikiwhat.page/kavramlar/litmus%20paper">Litmus paper</a> turns red in acidic solutions.
  • Base: <a href="https://www.wikiwhat.page/kavramlar/litmus%20paper">Litmus paper</a> turns blue in basic (alkaline) solutions.
  • Neutral: <a href="https://www.wikiwhat.page/kavramlar/litmus%20paper">Litmus paper</a> will remain purple (its original color) in neutral solutions.
• Types: <a href="https://www.wikiwhat.page/kavramlar/litmus%20paper">Litmus paper</a> comes in two main types: red litmus paper and blue litmus paper. Red litmus paper turns blue in the presence of a base, while blue litmus paper turns red in the presence of an acid.
• Limitations: <a href="https://www.wikiwhat.page/kavramlar/litmus%20paper">Litmus paper</a> only indicates whether a substance is acidic or basic; it doesn't give you the precise <a href="https://www.wikiwhat.page/kavramlar/pH">pH</a> value. For that, you'd need a <a href="https://www.wikiwhat.page/kavramlar/pH%20meter">pH meter</a> or <a href="https://www.wikiwhat.page/kavramlar/pH%20indicator">pH indicator</a>.
