● conduct a practical investigation to measure the pH of a range of acids and bases
● calculate pH, pOH, hydrogen ion concentration ([H+]) and hydroxide ion concentration ([OH–]) for a range of solutions (ACSCH102)
● conduct an investigation to demonstrate the use of pH to indicate the differences between the strength of acids and bases (ACSCH102)
● write ionic equations to represent the dissociation of acids and bases in water, conjugate acid/base pairs in solution and amphiprotic nature of some salts, for example:
– sodium hydrogen carbonate
– potassium dihydrogen phosphate
● construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases (ACSCH099)
● calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed[/cs_text][/cs_column][/cs_row][/cs_section][cs_section parallax=”false” separator_top_type=”none” separator_top_height=”50px” separator_top_angle_point=”50″ separator_bottom_type=”none” separator_bottom_height=”50px” separator_bottom_angle_point=”50″ style=”margin: 0px;padding: 45px 0px;”][cs_row inner_container=”true” marginless_columns=”false” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/1″ style=”padding: 0px;”][cs_text]Extract from Chemistry Stage 6 Syllabus © 2017 NSW Education Standards Authority (NESA)[/cs_text][/cs_column][/cs_row][/cs_section][/cs_content]
