Term 1 , week 4

This week you are to be practicing for the internal Achievement Standard 2.2. Make sure you arrange with your science teacher a suitable time for you to carryout the practical (early in week 5, must be completed before VC Friday 2nd March). I will be emailing them the task and requesting that you complete the activity this week.You are required to
  •  use a flowchart to identify ions
  • write balanced equations for the reactions where precipitates are formed
  • write balanced equations for the formation of complex ions.
As revision for this, click on attachments below and use your flowchart to identify the unknown ions and write balanced equations where precipitates form. The answers are also provided below. 
Work really hard at writing the balanced equations. The ones the concentrate on are the complex ions, see SG at bottom of p16.
This standard is relatively easy to gain Excellence in if you learn the complex ion reactions.
Look at the example assessment schedule in the attachments below.
