The formula here is:
pH = -log[H+]
3.6 = -log[H+]
[H+] = 2.51 x 10⁻⁴ mol / Liter
The first option is correct.
Answer:
Explanation:
(a)
Given that:
Rate constant, k = 0.0347 min⁻¹
The expression for the half-life is:-
Where, k is rate constant
So,
(b)
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
t = 60 min
Initial concentration = 0.300 M
Final concentration =?
Applying in the above equation, we get that:-
Answer:
1 strong acid
2 yes they are dangerous
Explanation:
Since nearly all of it is dissociated in water, it is called a strong acid.
2 yes Concentrated strong acids can cause severe and painful burns. The pain is due in part to the formation of a protein layer, which resists further penetration of the acid
Reduction is process carried out in a presence of reducing agent like hydrogen. Hydrogen is added to carbon adjacent to oxygen leding to formation of 3- methypentan-1-ol that is -CHO funtional group is reduced to OH functional group. 3-methylpentan-1-ol open structure is therefore
CH3CH2CH(CH3)CH2CH2OH
The pH of a solution of sulphuric acid that has hydronium ion concentration is 4.26.
<h3>How do we calculate pH?</h3>
pH of any solution is define as the negative logarithm of the concentration of H⁺ ion present in any solution, i.e.
pH = -log[H⁺]
In the question, it is given that:
Concentration of hydronium ion or H⁺ ion = 5.45×10⁻⁵ M
So, pH will be:
pH = -log(5.45×10⁻⁵)
pH = -(-4.26)
pH = 4.26
Hence required pH is 4.26.
