In any car there is a current source, this source is the accumulator. Since the accumulator is an element of reusable use, it is possible to recharge and change it in it electrolyte. Earlier, in cars both acid, and alkaline accumulators were used, but now remained only acid. Therefore electrolyte for them is prepared only on the basis of sulfuric acid, for a temperate climate electrolyte has density 1.27. For preparation of electrolytes pure acid, with a density of 1.84 is used.
It is required to you
- Two ebonite a container, the concentrated sulfuric acid, the distilled water, the areometer.
Instruction
1. Take the acidproof capacity for example made of ebonite and pour in it the distilled water. Then, carefully, a thin stream add the concentrated sulfuric acid to the distilled water, do not forget to mix at the same time solution any acidproof subject, for example, a glass stick.
2. In such a way bring solution to density 1.4, check density the areometer. When mixing acids with water, heat will be generated, temperature of solution will increase. After that let's solution cool down to room temperature.
3. Then, when solution will cool down, once again measure density. Pour the distilled water and already acid which has density 1.4 in other container, carefully pour in water, bringing electrolyte to density 1.27.
