1) Answer is: the hydrogen ion concentration is 1·10⁻¹ mol/L.
[OH⁻] = 1·10⁻¹³<span> mol/L, equilibrium concentration of hydroxide anion.
</span>[H⁺] is the concentration<span> of hydrogen ions.
</span>[OH⁻] · [H⁺] = 10⁻¹⁴ mol²/L², ionicproduct of water on room temperature.
[H⁺] = 10⁻¹⁴ mol²/L² ÷ 1·10⁻¹³ mol/L.
[H⁺] = 10⁻¹ mol/L = 0,1 mol/L.
2) pH = -log[H⁺], <span>approximately </span><span>the negative of the base 10 </span>logarithm<span> of the </span>molar concentration of hydrogen ions
pH = -log(10⁻¹ mol/L).
pH = 1.
This solution is acid, because pH value (potential of hydrogen) is less than seven. If pH is greater than seven, slotion is base and if pH is equal seven, solution is neutral.
Answer:
Concentrated sulfuric acid can perform a dehydration reaction with table sugar. After mixing, the color changes from white to brownish and eventually to black. The expansion of the mixture is the result of vaporization of water and CO2 inside the container.
Answer:
1 200 000 000 000 000 000 000 000 H⁺ ions
Step-by-step explanation:
Assume that the concentration of H⁺ ions in stomach ions is <em>2.0 mol·L⁻¹.</em>
Then, we have 2.0 mol of H⁺ ions
There are 6.02 × 10²³ H⁺ ions in 1 mol.
2.0 mol = 2.0 × 6.022 × 10²³/1
= 1.2 × 10²⁴ H⁺ ions
= 1 200 000 000 000 000 000 000 000 H⁺ ions
Answer:
the order is as follows:
London dispersion < Dipole-Dipole < H-bonds < Ionic bonds
