Answer:
75L of additional water to have a pH 1 solution
Explanation:
The reaction of HCl With NaOH is:
HCl + NaOH → H₂O + NaCl
By using molar mass of each reactant you can know how many moles will react, thus:
HCl: 364.6g HCl ₓ (1mol / 36.46g) = 10 moles HCl
NaOH: 80g NaOH ₓ (1mol / 40g) = 2 moles NaOH
That means after the reaction will remain in solution, 10-2 = 8 moles of HCl = 8 moles of H⁺ (In water, HCl dissociates as H⁺ and Cl⁻ ions).
A solution with pH = 1 contains:
pH = -log [H⁺]
1 = -log [H⁺]
0.1M = [H⁺]
As molarity, M is the ratio between moles and liters and you want a solution 0.1M having 8 moles of H⁺ you require:
0.1M = 8 moles H⁺ / 80L
As the student combines the solution with 5L of water, you require
<h3>75L of additional water to have a pH 1 solution</h3>
Well ionic compounds are brittle because similar charges repel, which causes them to break usually occurring when a force is applied, like a hammer strike.
M1V1 = M2V2
M1 = 3.000 M
V1 = 0.8000 L
M2 = ?
V2 = 2.00 L
M2 = M1V1/V2 = (3.000 M)(0.8000 L)/(2.00 L) = 1.20 M
Answer:
protons and neutrons are found in nucleus
