Question

What are the properties of acid

Answer 1

Answer:

Properties of Acids are :

1. 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.

2. Acids have a sour taste. Lemons, vinegar, and sour candies all contain acids.

3. 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.

4. 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)

5. 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.

Answer 2

$\huge\mathfrak\purple{Answer:-}$

What are are acids?

=> Acids are substances which dissociate in aqueous solution to give hydrogen ions or hydronium ions

($H_{3} O^{+}$)

Properties of acid :

1. They are sour in taste.

2. They turn blue litmus red.

3. They react with metals to evolve hydrogen gas.

4. They react with bases to form salt and water. This is neutralisation.

5. They react with basic oxides to form salt and water.

6. They react with metal carbonates and bicarbonates to form salt, water and carbon dioxide
