Answer:
Explanation:
Hello!
In this case, since the sulfuric acid and sodium hydroxide react in a 1:2 mole ratio, given the reaction, we realize they have the following mole ratio at the equivalence point:
Which in terms of concentrations and volumes is:
Thus, we can plug in the volume and concentration of acid to find the moles of base:
Best regards!
Answer:
HCl
Explanation:
Phosgene (COCl₂) on reaction with moisture in lungs converts into Carbon dioxide and hydrochloric acid.
COCl₂ + 2 H₂O → CO₂ + 2 HCl
The HCl produced in lungs causes problems. It reacts with alveoli proteins resulting in suffocation, coughing, eyes and throat irritation and difficulty in breathing.
<em>V = 151 mL = 151 cm³</em>
<em>d = 0,789 g/mL = 0,789 g/cm³</em>
--------------------------------------
d = m/V
m = d×V
m = 0,789×151
<u>m = 119,139g</u>
Answer:
,
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
Strong acids dissociate completely and thus, 0.5 M of a solution of a strong acid yields a pH of 1.0 .
The expression of the pH of the calculation of weak acid is:-
Where, C is the concentration = 0.5 M
Given, pH = 4.0
So, for ,
pH = 4.0
<u>Hence, the acid is HOCl.</u>
