POh is calculated by the negative logarithm of hydroxide ions concentration. From the given value, we have:

<span>pOH = -log(8.6 x 10 ^-5)
</span><span>pOH = 4.07
</span><span>
To calculate the pH we use the relation of pOH and pH, expressed as:
</span><span>
14 = pOH + pH
</span><span>pH = 14 - 4.07 = 9.93
</span><span>pH = -log [H+]
</span><span>[H+] = 10^-9.93 = 1.16 x 10^-3 M</span>

In the titration of a solution of Sodium hydroxide, an acid titrant was prepared by diluting 125.0 mL of 10.00 mol/L Nitric acid
harina [27]

Answer:

1.395M NaOH

Explanation:

Sodium hydroxide, NaOH, reacts with nitric acid, HNO3, as follows:

NaOH + HNO3 → NaNO3 + H2O

<em>Where 1mol of NaOH reacts with 1mol of HNO3</em>

To solve this question we must find the concentration of the titrant. With the concentration and the needed acid we can find the moles of HNO3 added = moles NaOH in the solution. With the moles of NaOH and its volume we can find its concentration as follows:

<em>HNO3 concentration:</em>

10.00mol/L HNO3 * (125.0mL/500.0mL) = 2.500M HNO3

<em>Moles HNO3 = Moles NaOH:</em>

16.74mL = 0.01674L*(2.500mol/L) = 0.04185 moles HNO3 = Moles NaOH

<em>Concentration NaOH:</em>

0.04185 moles / 0.0300L =

1.395M NaOH

konstantin123 [22]
The image represents A COMPOUND because the molecules are BONDED CHEMICALLY.
A compound is a substance formed when two or more elements combine together chemically. In the process of chemical combination, the chemical bonds that were present in the participating elements will be broken and new chemical bonds will be formed in the product.

Which of the following statements about trends in solubility is accurate?
Kipish [7]

"The solubility of gases decreases as temperature rises" statements about trends in solubility is accurate.

<u>Option: D</u>

<u>Explanation:</u>

A substance's solubility is the quantity of that component that is needed at a defined degree of temperature to produce a saturated solution in any set quantity of solvent. Some compounds like hydrochloric acid, ammonia, etc  have solubility that reduces with rising temperature. They are both standard-pressure gases.

When heating a solvent with a gas absorbed in it, both the solvent and the solute spike in the kinetic energy.When the gaseous solute's kinetic energy rises, the molecules have a higher propensity to overcome the solvent molecules' connection and migrate to the gas phase. Thus, a gas's solubility reduces with rising temperature.
