Five properties of acids

Answer 1

* Strong or concentrated acids often produce a stinging feeling on mucous membranes * React to indicators as follows: turn blue litmus and methyl orange red, do not change the color of phenolphthalein * Will react with metals to produce a metal salt and hydrogen * Will react with metal carbonates to produce water, CO2 and a salt * Will react with a base to produce a salt and water * Will react with a metal oxide to produce water and a salt * Will conduct electricity, depending on the degree of dissociation * Will produce solvonium ions, such as hydronium (H3O+) ions in water * Will denature proteins * Generally sour tasted Strong acids and many concentrated acids are dangerous, causing severe burns for even minor contact. Acids are corrosive. Generally, acid burns are treated by rinsing the affected area abundantly with running water (15 minutes) and followed up with immediate medical attention. In the case of highly concentrated acids, the acid should first be wiped off as much as possible, otherwise the exothermic mixing of the acid and the water could cause severe thermal burns. Acids may also be dangerous for reasons not related to their acidity, see an appropriate MSDS for more detailed information.

Answer 2

1. Acids are substances that can donate hydrogen ions (H+).
2. Acids have a sour taste and can turn blue litmus paper red.
3. Acids react with bases to form salts and water.
4. Acids can conduct electricity when dissolved in water.
5. Acids can corrode certain metals.

Answer 3

• acids taste sour
• can be extremely corrosive
• contain one or more hydrogen atoms

Answer 4

Apex- react with litmus paper and turn it read, produce a painful/burning sensation on skin

Answer 5

-it tastes sour

-reacts with metals

-reacts with carbonate

-turns blue litmus paper red

:]

Answer 6

1. Corrosive

2. Sour taste

3. Neutralises base

4. Contain Hydrogen (H+) ions

5. Has pH less than 7

Answer 7

1) Acids have a low pH.

2)Acids taste sour.

3)Acids can be corrosive.

4)Acids are neutralised by alkalis

5)Acids make hydrogen

6)Acids make Carbon Dioxide

Answer 8

Tastes sour, turns litmus paper red, conduct electricity, very corrosive to metals, react with metals, And react with bases to produce salt and water
