1. 0 to 6 is considered a _. 7 is considered a _. 8 - 14 is considered a _
2. when a base and acid are mixed together _

Explanation:

On the pH scale, values from 0 - 6 indicate acidity due to higher hydrogen - ion concentration. A pH of 7 is neutral as the hydrogen - ion and hydroxide - ion concentrations are equal. Values from 8 - 14 are basic as they have a higher hydroxide - ion concentration. When an acid and a base are mixed, a neutralization reaction occurs, producing salt and water.
