how to identify spectator ionsBlog

how to identify spectator ions

These ions are called spectator ions since they don't participate in the chemical reaction at all (they just "watch"). Strong acids do affect pH, because placing a strong acid into water will cause it to ionize and lower the pH of the solution. These states tell whether the ions have changed their states from reactants to products thus determining the spectator ions. These are shown in Table 2: All the images are created using Geogebra. The cation in the solution can be either Na+, Ba2+, Ag+, or Ni2+. Including the state symbol, identify the spectator ion in this reaction. The user can follow the steps given below to use the Spectator Ions Calculator. Carbonates react with dilute acids to form carbon dioxide gas. Diagnostic multiple-choice questionsare a great way to explore learners misconceptions by investigating reasoning behind their answers. If all reactants and products cross out, then no reaction will occur.

The net reaction is

As written, the preceding reaction is imbalanced with respect to the number of hydrogen atoms and the amount of positive charge.

Balance the net reaction for mass and charge.
