chemistry

• Acids can react with metals to produce hydrogen gas.
• Acid + Metal Carbonate → Water + Salt + Carbon Dioxide
• The reaction between an acid and metal carbonate produces water, salt, and carbon dioxide.
• Metal + Acid → Salt + Hydrogen
• Acid + Metal Sulfide → Water + Salt + Sulphur Dioxide
• Acid + Metal Oxide → Water + Salt
• Metal oxides are basic substances that neutralize acids by forming salts and water.
• When an acid reacts with a base (metal oxide), it forms a salt and water.
• A neutralization reaction is the combination of an acid and a base to form a salt and water.
• When an acid reacts with a metal, it forms a salt and releases hydrogen gas.
• Reaction between an acid and metal sulfide produces water, salt, and sulfur dioxide.
• Acid + Metal Chloride → Water + Salt
• Acid + Metal Nitrate → Water + Salt
• The pH scale measures how acidic or alkaline a solution is, ranging from 0-14.
• Stronger acids have lower pH values than weaker ones.
