To check the specific gravity of acid in a car battery, you'll need a hydrometer. First, ensure the battery is fully charged and then carefully remove the vent caps. Insert the hydrometer into the electrolyte solution, squeezing the bulb to draw in the liquid, and then release it to allow the float to settle. Read the specific gravity measurement on the scale; a higher value typically indicates a fully charged battery, while a lower value suggests it's discharged.
When a battery is fully charged, the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3. The answer is C. I found this on Page 78 of the Mechanics Study Unit of Physical Science (Penn Foster). One of the uses of a hydrometer is to measure the condition of electrolyte solution in a storage battery of the type used in a car. When a battery is fully charged, the amount of sulfuric gravity of about 1.3.
when a battery is fully charged , the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3 when battery is discharged to 50 percent, the specific gravity reading should be 1.2 any specific gravity reading that's less than 1.1 usually indicates a dead batteryThe answer isC. 1.3.
Specific gravity of the electrolyte in the lead acid cell or battery (assuming that the battery is not of the sealed type) is often used as a measure of its STATE OF CHARGE. Sure we can do the same with a multimeter but the above method is more accurate.

A battery hydrometer which measures the specific gravity (relative density) of liquids, to determine the concentration of sulfuric acid in each cell.
This is very difficult. The old way was to check the specific gravity of the acid/water mixture in the individual cells. You need a voltmeter and know how to use it to check a battery. 35 Percent of battery replacements are unescellaly made because poor connections in the vehicle's charging system, but corrected when you buy the new battery.
No.AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)

In a car battery, the acid solution is called electrolyte. It is typically a mixture of sulfuric acid and water that helps facilitate the flow of electrical current between the battery's positive and negative terminals.
Yes, that is true. As a battery discharges, the concentration of sulfuric acid in the electrolyte decreases, leading to a decrease in density or specific gravity. This change in electrolyte density can be used as an indicator of the state of charge of the battery.
The acid used is generally Sulphuric Acid. You cannot change it to another type of acid such as "Citric" Yes you can change it, but why do you want to? I WOULD NOT recommended it for anyone not trained how to do it. In any case if the acid is depleted the battery will most likely be useless too. Perhaps you should check the specific gravity and add DISTILLED water as necessary, about 5mm above the plates should be OK.
Battery electrolyte consists of sulphuric acid, which is a liquid to a specific gravity of 1250 g/L.
