topic 16- further acid theory

• bases are proton accepters as they will react to form negative oh ions, these oh ions make the aqueous solution alkali
• acids are proton donors as they will react to form positive h ions, these h ions make the aqueous solution acidic
• alkalis in aqueous solution are a source of hydroxide ions
• litmus solution, colour in acid red, colour in alkaline blue
• acids in aqueous solutions are a source of hydrogen ions
• phenolphtaien, colour in acid colourless, colour in alkaline pink
• methyl orange, colour in acid red, colour in alkaline yellow
