The quantity pH stands for the negative logarithm of the H⁺ ions concentration in a solution. In equation form, pH = -log[H⁺], where [H⁺] is the concentration of hydrogen ion in molarity or moles/liter. Using this definition, the pH of the following substances are:

Oven Cleaner: pH =-log(10⁻¹³ M) = 13
Water: pH = -log(<span>0.0000007 M) = 6.15
Blood: pH = -log(</span><span>0.00000004 M) = 7.40
Vinegar: pH = -log(</span><span> 0.0063 M) = 2.2

The measure of the pH is important when it comes to reactions because pH is a strong factor. The net charge of a substance is a result of its pH. This charge is the basis of the degree of intermolecular forces like electrostatic attraction due to difference of charges by the substance and its substrate.</span>

Volume of a gas at STP, if its volume is 80.0 mL at 1.08 atm and –12.5oC.
vodomira [7]

Answer:

90.5mL is the volume of the gas at STP

Explanation:

It is possible to find volume of a gas when conditions of temperature and pressure change using combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

Where P is pressure, V is volume and T is absolute temperature. 1 is initial conditions and 2 final conditions.

If initial conditions are 1.08atm, 80.0mL and absolute temperature is (-12.5°C + 273.15) = 260.65K.

And STP are 1atm of pressure and 273.15K of absolute temperature. Replacing:

\frac{1.08atm80.0mL}{260.65K} =\frac{1atmV_2}{273.15K}

V₂ = <em>90.5mL is the volume of the gas at STP</em>
