Which type of acid is used in car batteries
Acid in the solution. Chemicals or substances having the property of an acid are said to be acidic. Common aqueous acids include hydrochloric acid (a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes), acetic acid (vinegar is a dilute aqueous solution of this liquid), sulfuric acid (used in car batteries), and citric acid (found in citrus fruits). As these examples show, acids (in the colloquial sense) can be solutions or pure substances, and can be derived from acids (in the strict sense) that are solids, liquids, or gases. Strong acids and some
Slot car and the grooves for the power strips cut directly into the base material using a router or CNC machining. This provides a smooth and consistent surface, which is generally preferred for serious competition. Power for most slot car tracks comes from a power pack. Power packs contain a transformer, which reduces high voltage house current to a safe 12 to 20V, depending on car type) and usually a rectifier, which changes AC to DC, for cooler running and simpler motors. High-capacity lead-acid batteries are sometimes used for hobby slot cars. Toy race sets may use dry cell batteries at 3
