Clarification Statement - S.HS.PS.1.11.CS:
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 - S.HS.PS.1.11.AB:
Reactions are limited to Arrhenius and Bronsted-Lowry acid-base reactions.

Science and Engineering Practices - 9-12.SEP3.1:
Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on t

Science and Engineering Practices - 9-12.SEP3.2:
Select appropriate tools to collect, record, analyze, and evaluate data.

Disciplinary Core Ideas - S.HS.PS.1.11.DCI:
PS1.B: Chemical Reactions •(NYSED) Acids and bases play an important role in the daily lives of humans and other organisms (e.g. agricultural applications, environmental impacts (acid rain), animal and plant physiology).

Crosscutting Concepts - CC1.13:
Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
