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:
Chemical properties would be like what you would make food with because you are changing the structure of the ingredients.
Physical properties would be like a chair or the device you asked this question on.
Explanation:
the semipermeable membrane surrounding the cytoplasm of a cell.
The answer is A because it does not represent a redox reaction
AlBr3(aq) is an ionic compound which will have the releasing of 3 Br⁻ ions ions in water for every molecule of AlBr3 that dissolves.
AlBr3(s) --> Al+(aq) + 3 Br⁻(aq)
[Br⁻] = 0.16 mol AlBr3/1L × 3 mol Br⁻ / 1 mol AlBr3 = 0.48 M
The answer to this question is [Br⁻] = 0.48 M
