CHAPTER 13

CHAPTER 13. Acids and Bases. 13.2 The pH Scale. Soil at a high pH makes hydrangea flowers pink. Soil at a low pH makes hydrangea flowers blue. pH range. pH can be less than 0 for stronger acids greater than 14 for stronger bases. Water is neutral: [H + ] = 1 x 10 -7 M and pH = 7.

ACIDS AND BASES

ACIDS AND BASES. CLENT MARK C. GAITERA JOHN ALEX C. OCAY. 1. What are the physical and chemical behavior of acids and bases?. Acids Taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases. Bases

pH Scale & Indicators

pH Scale & Indicators. pH Scale. pH Scale : Expresses the strength of acids and bases One pH unit = an inc/dec in [H 3 O + ] by a ten fold Neutral = 7 Acid < 7 Base > 7. Calculating pH. pH = -log[H 3 O + ] pOH = -log[OH - ] pH + pOH = 14. Calculating the pH. pH = - log [H+]

5.1 Acids and Bases

5.1 Acids and Bases. Acids and bases are very common. Many familiar compounds are acids or bases. Classification as acids or bases is based on chemical composition. Acids and bases can be very dangerous! Both can be very corrosive. NEVER try to identify an acid or base by taste or touch!
