First calculate the Molarity <span>of the final solution :
C</span>₁ = 6.0 M
V₁ = 25 mL
C₂ = ?
V₂ = 1.75 * 1000 = 1750 mL
C₁ * V₁ = C₂ * V₂
6.0 * 25 = C₂ * 1750
150 = C₂ * 1750
C₂ = 150 / 1750
C₂ = 0.08571 M
Therefore:
pH = - log [C₂]
pH = - log [ <span>0.08571 ]
</span>
pH = 1.0669
hope this helps!
A. The nervous system works without the aid of other systems in order to provide a sufficiently rapid response.
<span>An acidic solution has only hydrogen ions and a basic solution has only hydroxide ions </span>statement correctly distinguishes between an acidic and a basic solution
N-Octanol and water are chosen because the connection between a substance's hydrophilicity and lipophilicity is measured by 
(n-Octanol/Water partition coefficient). When a chemical is more dissolves in fat-like solvents like n-octanol, the value is more significant than one, when it's more dissolved in water, the value is lower.
What is the partition coefficient?
- The partition coefficient for the two-phase network comprising n-octanol and water is known as the value. N-Octanol-Water Partition Ratio is another name for it.
- The connection between a substance's hydrophilicity (its ability to dissolve in water) and lipophilicity (its ability to dissolve in fat) is measured by . The value is bigger if a drug is more accessible in fat-like liquids like n-octanol and less if a compound seems more water-soluble.
- Owing to linkage or fragmentation, substances that are involved in the octanol-water combination as multiple synthetic entities are each given a unique ratio.
So, N-Octanol is chosen because it has a carbon/oxygen ratio that is comparable to that of lipids and because it shows both hydrophobic and hydrophilic properties. N-octanol, therefore, resembles the makeup and characteristics of cells and other living things.

1.Strong basses dissociates into ions almost 100%.
But weak basses partially dissociates into ions.
2.Strong basses has pH value smaller but closer to 14 and weak basses has pH value greater but cloaer to 7.
3.strong basses ate highly reactive whereas weak basses are less reactive.
