Question

1) Wasp stings are alkaline and can be neutralized with vinegar. Can you explain why?

2)Give two examples of dilute and concentrated acids.

3)What are the differences between dilute and concentrated acids?

Answer 1

1. . Wasp sting venom is alkaline and so its effects can be neutralised with vinegar or acid and this neutralisationthen reduces the pain. ... Bee sting venom is acidic and so its effects can be neutralised with bicarbonate of soda or alkali and this reaction reduces the pain.
2. week= vinegar,nitrous acid &strong=hcl,h2so4
3. A concentrated acid has a relatively large amount of solute dissolved in the solvent. A dilute acid has a relatively smaller amount of solute dissolved in the solvent. 3. In a solution of a strong acid there would be solvated ions present, but no (or only a very small proportion of)associated molecules present

Answer 2

1 ). Wasp stings are alkaline ( basic ) in nature. So, they can be neutralised with vinegar because vinegar is acidic in nature and contains acid. The reaction between acid and base neutralises the the reaction.

2 ). Dilute acids : CH3COOH, C2H5OH

Concentrated :HCL, H2SO4

3 ). Dilute acids : The concentrated acids which are diluted by adding much amount of water more than their concentration,such are called dilute acids. They are harmless.

Concentrated acids : Concentrated acids are pure acids in which water is not added to dilute them. It has high Molar concentration of H+ ions. They are harmful acids.
