Titration

Titration. Titration of a Strong Acid by a Strong Base. Consider what happens to the pH of 25 mL of 0.2 M HCl as it is titrated with 25 mL of 0.2 M NaOH . This result is shown in the diagram to the right. The diagram is referred to as a ___________________ _____________.

Ionisation of water and pH

pH concept pH = -log[H + ] pX = -logX. Ionisation of water and pH. pH scale [H + ] > 10 -7 M, pH < 7 ACIDIC [H + ] < 10 -7 M, pH > 7 BASIC [H + ] = 10 -7 M, pH = 7 NEUTRAL. For any Bronsted conjugate Acid-Base pair. K a . K b = K w. CH 3 COOH ?H + +CH 3 COO -. Buffers.

pH ( power of hydronium ion)

pH ( power of hydronium ion). The pH scale is a way of expressing the strength of acids and bases. Instead of using very small numbers, we just use the NEGATIVE power of 10 on the Molarity of the H + (or OH - ) ion. Under 7 = acid 7 = neutral Over 7 = base. pH = -log[H + ].

Acids and Alkalis

Acids and Alkalis. What are acids and alkalis?. What are indicators?. Indicators are chemicals that change colour in the presence of an acid or an alkali. There are many different indicators. Many of them come from plants, like red cabbage. Different indicators turn different colours.

The pH scale

The pH scale. p H. Measure of acidity of a solution 0 to 14 Water is neutral because of equal amounts of hydrogen and hydroxide ions . Acidic solution has excess of hydrogen ions . Alkaline soltion has excess of hydroxide ions. pH means power of hydrogen.
