17. Acid and Base Equilibrium

pH and pOH

Calculating the pH of a Strong Acid and Strong Base

If the pH is less than 7 then the solution is acidic, if the pH is equal to 7 then the solution is neutral and if the pH is greater than 7 then the solution is basic.&#160;

If we know the pH or pOH concentration then we can determine the concentration of hydronium ions or hydroxide ions.&#160;

Calculate the pH of 50.00 mL of 4.3 x 10-7&nbsp;M H2SO4.

0.100 moles C6H5NH2

0.100 moles (CH3)2NH

Which of the following solutions will have the lowest concentration of hydronium ions?

The ionization product of Kw is used in this self-ionization equation and ignoring solids and liquids gives the&#160; equilibrium equation as:&#160;

pH stands for the negative logarithmic function of your hydronium concentration, whereas pOH stands for the negative logarithmic function of hydroxide concentration.&#160;

If we have a <a href="https://www.clutchprep.com/chemistry/strong-acids-and-strong-bases">STRONG ACID&nbsp;or STRONG BASE</a> then we DO NOT use an ICE chart to find the pH of solution because the yield of H+ and OH – &nbsp;ions are known.&nbsp;

Determine the pH of a solution made by dissolving 6.1 g of sodium cyanide, NaCN, in enough water to make a 500.0 mL of solution. (MW of NaCN = 49.01 g/mol). The Ka value of HCN is 4.9 x 10-10.

For an basic solution the concentration of H3O+ is greater than the concentration of OH-.

The pH of a neutral aqueous solution is 7.00 at all temperatures.

An acidic solution under normal conditions has a pH value less than 7.00.

If the concentration of H3O+ decreases then the concentration of OH- will also decrease.

The pH of aqueous solutions is less than 7.

Which of the following statements about aqueous solutions is/are true?

Under normal conditions when the concentration is less than 1.0 M the pH scale is between 0 to 14. pH and pOH are connected by the following equation:&#160;

The pH and pOH of a compound helps to determine its acidity and basicity.&#160;

To determine the pH of a weak acid or weak base we must use an ICE Chart.&#160;

If we have a WEAK ACID or WEAK BASE then we DO use an ICE chart to find the pH of solution because the yield of H+ and OH &#8211; &#160;ions are unknown.&#160;

In a self-ionization reaction two water molecules react with one another, where one acts an acid and the other as a base.&#160;

What is the Kw of pure water at 20.0°C, if the pH is 7.083?
