ph-scale 0.00.20

Click to launch English version:

• pH Scale

What's new:

• use consistent colors for H2O, H3O and OH throughout (water, bars, molecules, particles, pH slider)
• adjust color of H2O molecule image (done by Archie)
• minor tick marks on beaker at 0.1L increments
• maximum beaker volume of 1.2L
• label only the 1/2L and 1L ticks on beaker
• volume readout that moves up the outside right edge of the beaker
• beaker is 15 pixels narrower to make room for volume readout
• add linearly variable flow rate to the faucets
• major model changes to support variable flow rate
• limit volume precision to 2 decimal places in the model, so that student calculations match what is displayed
• tweak clock framerate and faucet flow rates to support titration precision, while keeping fill/drain animation reasonably smooth (clock rate = 10 ticks per second, fastest flow = 1L/sec, liquid selection flow = 0.75L/sec)
• delete alternate "molecule counts" view, colors of its H2O image file was now out of date

Know issues:

• none
