Essential question: How can logarithmic scales and stoichiometry quantify acidity?
A tiny change in hydrogen-ion concentration produces a large pH shift.
Build an initial model and explanation for: How can logarithmic scales and stoichiometry quantify acidity?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: pH; pOH; strong/weak; equivalence; indicator.
Study and explain the week's core ideas: pH; pOH; strong/weak; equivalence; indicator
Open text on pH and titration.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
pH calculations and titration stoichiometry at appropriate level.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How can logarithmic scales and stoichiometry quantify acidity?
Virtual titration; supervised neutralization only in equipped lab.
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How can logarithmic scales and stoichiometry quantify acidity?
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Select one artifact from this week and explain why it is trustworthy evidence of growth.
