Answer:
2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.
Explanation:
- This is an acid-base reaction which produces salt and water according to the balanced equation:
<em>2KOH + H₂SO₄ → K₂SO₄ + 2H₂O.</em>
<em></em>
it is clear that 2.0 moles of KOH react with 1.0 mole of H₂SO₄ to produce 1.0 mole of K₂SO₄ and 2.0 moles of H₂O
Answer : The property in the wrong column is, base form hydrogen gas with metals
Explanation :
Acid : It is a substance that has ability of donating a proton or hydrogen ion,
.
The properties of an acid are :
- Acids are sour in taste.
- It conduct electricity.
- The texture of an acid solution is sticky.
- It react with carbonates to give salt.
- It changes the color of the litmus paper to red.
- It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion,
.
The properties of an base are :
- Base are bitter in taste.
- It conduct electricity.
- The texture of an base solution is slippery.
- It changes the color of the litmus paper to blue.
- It does not react with a metal.
Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals
.
