pH
1. What is PH? The pH is a measure if how acidic or basic the solution is. 2.What are PH values? The pH scale generally ranges from 0 to 14. · The acid solutions have lower pH values. · The basic solutions have higher pH values. · A Solution with a pH of 0 is highly acidic. · A solution that has a pH of 7 is neutral. · A solution with pH of 14 is extremely basic. Do these values depend on something? Explain your answers. The pH of a solution is directly related to its concentrations of hydronium ions and hydroxide ions. · The acid solutions have more hydronium ions than hydroxide ions. · The basic solutions have more hydroxide ions than hydronium ions. · The neutral solutions have equal numbers of two ions. 3. Check Chart 3.20 about acids and bases. What can you explain about it? The pH scale is not a simple linear scale like mass o volumen. A change of a 1
