IS. To prepare for laboratory: For each of the eight unknowns solutions that you will identify in lab (see above or table below), identify the chemical color and the pH category (acidic, neutral, or basic) that you expect to find. Prepare a table to summarize your initial expectations for the color and pH tests. Introduction- A Fistitious Ssenario

Part A Reset Help significant When determining the pH of a polyprotic acid solution or mixture of acids, only the [OH | acid needs to be considered. Any another other ionizations are by comparison, and ion content. the overall negligible must be considered in does not contribute to strongest weakest [H;O]+

If the pH of a solution is 3.3, then the pOH is ( Select ] and the solution is [ Select ]
