About

CloudLabs Acid

Features
Read full description

In this practice, it is possible to measure the heat released by a neutralization reaction and to find its enthalpy. It is necessary to balance the energy of the acid and the base to an equilibrium point. To do so, the simulator recreates a laboratory with a calorimeter, a heating plate, a universal support, thermometers, a flask with an acid and a flask with a base (sodium hydroxide) as well as other materials and supplies to complete this practice.

Verdict

The call

The clearest difference is update cadence: AeroEngineS at every 3 days against CloudLabs Acid's every 28 months. CloudLabs Acid's advantage is iOS requirement (9.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.
