Acids are very common in some of the foods that we eat. Citrus fruits such as oranges and lemons contain citric acid and ascorbic acid, which is better known as vitamin C. Carbonated sodas contain phosphoric acid. Vinegar contains acetic acid. Your own stomach utilizes hydrochloric acid to digest food.

Acids are a distinct class of compounds because of the properties of their aqueous solutions. Those properties are outlined below:

Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. Some acids are strong electrolytes because they ionize completely in water, yielding a great many ions. Other acids are weak electrolytes that exist primarily in a non-ionized form when dissolved in water.
Acids have a sour taste. Lemons, vinegar, and sour candies all contain acids.
Acids change the color of certain acid-base indicates. Two common indicators are litmus and phenolphthalein. Blue litmus turns red in the presence of an acid, while phenolphthalein turns colorless.
Acids react with active metals to yield hydrogen gas. Recall that an activity series is a list of metals in descending order of reactivity. Metals that are above hydrogen in the activity series will replace the hydrogen from an acid in a single-replacement reaction, as shown below:
Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)(21.1.1)(21.1.1)Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)
Acids react with bases to produce a salt compound and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The products of this reaction are an ionic compound, which is labeled as a salt, and water.

Let us assume that √13 is rational no and equals to p/q are Co primes √13=p/q squaring both sides √13*2=p*2/q*2 13=p*2/q*2 13q*2=p*2 13/p*2 13/p p=3r for some integer r p*2=169r*2 13q*2=169*2 b*2=13r*2 13/b*2 13/b 13 is a common factor but this is contradiction hence our supposition is wrong √13 is irrational no.

Giuseppe Mazzini was an Italian revolutionary. He was born in 1807. He became a member of the secret society of the Carbonari. When he was 24 years old, he was sent into exile in 1831 for attempting a revolution in Liguria. After that, he founded two more underground societies; first Young Italy in Marseilles and then Young Europe in Berne. Mazzini believed that God had intended nations to be the natural units of mankind. So Italy had to be forged into a single unified republic instead of being a patchwork of small state kingdoms. Following in the footsteps of Mazzini, many secret societies were set up Germany, France, Switzerland and Poland. The Conservatives feared Mazzini. While the conservative regimes were trying to consolidate their power, the liberals and nationalists continued to spread the idea of revolution.
