1) The document discusses acids, bases and neutrals. It defines acids as substances that donate protons and increase hydrogen ion concentration in water, while bases accept protons and increase hydroxide ion concentration. 2) Acids are described as having a sour taste and being sticky, while bases are bitter with a slippery texture. Acids can be solids, liquids or gases depending on temperature, while bases are mostly solids except for ammonia. 3) When acids and bases of equal strength are added to a solution, the solution will remain neutral as the chemical properties of the acids and bases destroy each other.

Mr A. Mxadi ACIDS, BASES AND NEUTRALS
Lets Think for a moment. Q: There is a clerk at the butcher shop, he is five feet ten inches tall, and he wears size 13 sneakers. What does he weigh? A: Meat. Q : Achmat have a loaf of bread, every time he eat it, he eat a half (1st half of loaf then half of the remained bread each time ). How long will it take him to finish the bread? A: 1). How would I know? 2). After 3 time 3).never finish 4). After 4 times
