Precipitation / Ksp / Selective Ion Separation Solver

Overview

Calculate ion product, precipitation status, molar solubility, common-ion effects, and selective precipitation thresholds. It is in the Chemistry Problem Solvers category and is intended to solve common chemistry calculation and reasoning tasks with transparent intermediate steps.

When To Use It

• You need a focused workflow for precipitation / ksp / selective ion separation solver without leaving ChemistryAtlas.
• You want a result that can be saved, shared, or chained into another chemistry app.
• You want the calculation assumptions and limitations visible next to the output.

Inputs

• text - Chemistry input - type: textarea - Use formulas, names, SMILES-like text, reactions, or key=value options. Heavier engines will plug into this same app surface.

Recommended Workflow

• Enter the problem statement or structured values, run the solver, then compare each intermediate step with your class, SOP, or lab notebook conventions.
• Start with the smallest representative input, confirm the parser understood it, then scale to a larger list or workflow.
• Save the generated report when the result will feed a notebook entry, route review, model comparison, or team discussion.

Outputs

• A Markdown-style chemistry report with parsed inputs, assumptions, and calculated or predicted results.
• Structured tables when the app returns multiple compounds, reagents, routes, peaks, candidates, or model rows.
• Warnings, fallback notes, and sidecar availability messages when a specialized engine is not installed or not reachable.

Method And Backend Notes

This app has a runnable ChemistryAtlas backend path. Backend type: utility. ChemistryAtlas roadmap MVP: runnable report now; specialist cheminformatics/model backend plugs into this app surface next. The worksheet is designed to be auditable: keep units explicit, check limiting assumptions, and copy the final calculation trail into your notebook.

How To Interpret Results

• Use the explanation to audit the method; for graded or regulated work, show your own checked calculation trail.
• Compare results across related molecules, controls, blanks, literature examples, or known reactions whenever possible.
• For decisions that affect safety, synthesis scale-up, biological testing, purchasing, or publication, verify with primary data and expert review.

Example Input

salt=Mg(OH)2
ksp=5.6e-12
cation_m=0.01
anion_m=1e-5
cation_stoich=1
anion_stoich=2

Common Checks Before Acting

• Confirm names, salts, stereochemistry, tautomers, protonation state, and hydration state.
• Check units, concentrations, equivalent definitions, and significant figures.
• Record external database versions, model versions, sidecar availability, and any manual edits made after the app output.

Acknowledgements And Validation

• ChemistryAtlas documentation and UI were prepared for chemistry discovery workflows.
• Where available, calculations may use open-source cheminformatics, reaction-informatics, spectra, docking, or machine-learning engines such as RDKit-family tooling, ASKCOS-style sidecars, ChemProp, ms-pred/ICEBERG, PyScreener, and MolPAL.
• Always verify important results against primary literature, official SDS records, instrument software, validated models, and local laboratory procedures.
