using chemical properties distinguish acids and salt
Answers
There ph values
Answer:
Acids change the colour of litmus from blue to red.
They convert the colour of Methyl Orange from Orange/Yellow to Pink.
Acids turn the pink colour of Phenolphthalein to colourless.
Acids can conduct electricity.
Some Acids are highly corrosive in nature which means that they corrode or rust metals.
Acids tend to evolve hydrogen gas whilst reacting with an active metal such as Zn, Mg, etc.
They produce H+ ions when mixed with water.
Acids lose their acidity when mixed with a base.
When equal amounts of acid and base are combined the process of neutralization occurs and salt and water is formed,
The pH value of acid is from 0-6. Learn the concept of pH value here.
Acids are sour in taste.
Acids react with carbonates and hydrogen carbonates to form a salt, water, and carbon dioxide gas.
Extremely active metals such as Potassium (K), Calcium (Ca), Sodium (Na), etc tend to explode when combined with acids.
Weak Acids like Carbonic Acid doesn’t act with any metal at all.
Nitric Acids doesn’t usually exhibit acidic properties, it exhibits oxidizing properties instead.
Metals that generally react with dilute acid to form salt and hydrogen are the metals which lie above hydrogen in the metal activity series.
Acids form a salt, water and sulphur dioxide while reacting with sulphites and bisulphites.
Acids and metal sulphides form salt and hydrogen sulphide.
They are classified on the basis of their sources, strength, concentration, the presence of oxygen and its basicity.
The different types of acids are organic acids, mineral acids, strong acids, weak acids, concentrated acids, dilute acids, Oxy-acids, Hydracids, monobasic acids, dibasic acids, and tribasic acids.
