Chemical Properties of Acids and Alkalis

• Acids physically have a sour taste, are corrosive, less than 7 in pH value, and turns litmus paper red.
• Alkalis physically have a bitter taste, feel soapy, more than 7 in pH value, and turns litmus paper blue.
• Acids + bases/alkalis = salts + water.

  Acids + metal carbonates = salts + water + CO2.

  Acids + reactive metals = salts + hydrogen gas, H2.
