ACID-BASE AND SALT
Answers
Explanation:
1) Non-metals react with oxygen to form non-metal oxides. ... If an element forms a basic oxide,then the element will be a metal. If an element forms an acidic oxide,then the element will be a non-metal. Metal oxide are basic in nature and form bases on dissolving in water
2)Acids and bases have corrosive properties. ... -Thus, acids are carefully stored in glass containers due to their chemical inertness towards the acid because of which glass does not react chemically with most of the aqueous substances like acids
3) Sodium hydroxide (NaOH) – often called "caustic soda" Potassium hydroxide (KOH) – commonly called "caustic potash" Lye – generic term for either of two previous salts or their mixture. Calcium hydroxide (Ca(OH)2) – saturated solution known as "limewater"
4) Reaction with calcium carbonate. Calcium carbonate reacts with acids to produce a calcium salt, water and carbon dioxide: calcium carbonate +hydrochloric acid → calcium chloride + water + carbon dioxide.
5) less than 7
