Answer:
<h3>Chlorine </h3>
It has 7 electrons in it last shell. it will gain one electron to complete its octet and become Cl-. The ionic bond of chlorine form with potassium is Kcl ( potassium chloride)
- Phosphorus has 5 electrons in its last shell it need 3 more electron to stable .
- Sulphur has 6 electron. it needs 2 electrons
- Argon is already stable as it has 8 electrons in its last shell it will not gain or loose any electrons
Answer:
4.46
Explanation:
Applying,
pH = -log(H⁺)....................... Equation 1
Where H⁺ = Hydrogen ion concentration of HCl solution
From the question,
Given: H⁺ = 3.5×10⁻⁵ M
Substitute these values into equation 1
pH = -log(3.5×10⁻⁵)
pH = 4.46
Hence the pH of HCl solution is 4.46
