What are acids?
Acids are proton donors. They release H+ ions when dissolved in water.
Name the salt formed in the reaction of Sodium Hydroxide and Hydrochloric acid
Sodium Chloride
What are the products of the reaction between acids and metals?
Salt +Hydrogen
I am a device that gives the exact pH value of a substance. What am I?
pH meter
Which of the following pH represents a is a stronger acid?
PH 0.9
PH 5
PH 0.9 is a stonger acid
Substances that release Hydroxide ions in solution. These OH ions then bind to the H+ ions in from acids to make water.
Bases
How are salts named?
The first part of the name takes the name of the metal while the second part of the name is determined by the acid.
Explain one way that scientists can confirm the presence of carbon dioxide during the reaction of an acid and a carbonate.
Bubble the gas through lime water. Carbon dioxide should turn the gas cloudy.

Salt +WaterWhat is the colour of methyl orange in acids.
Methyl orange is red in acids
Differentiate between strong acids and weak acids
Strong acids ionize completely when dissolved in water while weak acids ionize partially.
I am an acidic oxide. What are acidic oxides?
Acidic oxides are oxides of non-metals. they form acidic solutions when dissolved in water. they are also called acid anhydrides.
Name the salt commonly known as table salt.

What is the products formed in the reaction of bases with ammonium compounds?
What are indicators?
These are substances that change colour to determine the whether a substance is acidic or basic.
Define Neutralization point
The point at which the acid or base is just used. The neutralization point has a PH of 7
Differentiate between aqueous and non-aqueous solutions
Aqueous means water is present while non-aqueous means no water is present.
