HS-PS1-11
Plan and conduct an investigation to compare properties and behaviors of acids and bases.
Clarification statement: Examples of properties could include pH values (concentration), neutralization capability and conductivity. Observations of behaviors could include the effects on indicators, reactions with other substances, and efficacy in performing titrations.
Assessment boundary: Reactions are limited to Arrhenius and Bronsted-Lowry acid-base reactions.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.
