2. Simulations are powerful techniques that duplicate or replicate complex real life situations. Learners learn about the real world. The major implication for learning with simulations is that the learner actually performs activities that are similar to those in reality. Simulations can be divide into two main groups: those that teach about something and those that tech how to do something.

3. Add about 3 to 4 point from methyl red by Eye dropper to20ml NaOH in Beaker.

4. Now, what you see? Yes, the solution's color to change from white to yellow.

5. Now, add 30ml HCL from Buret to solution in Beaker.

6. This is called equal point. The interaction equation: NaOH + HCL = NaCl +H2O The color change from yellow to red. Exit Continue
