Yes reacts with the CO2 in air when left open sitting out causing acidity.
no
NO
When an acid is mixed with water, there is usually no visible change, but the acid becomes less concentrated.
car battery's are filled with a special acid electrolyte which is 65% water however if the level drops it is ok to top them up with distilled water the water doesn't turn to acid it just mixes with the acid
Its a chemical change. its like an acid reacting with a base to form salt and water.
Chemical change
Add an acid or a base to it.
The pH of the hydrochloric acid does not change when it is added to water since it is already highly acidic. The concentration of the acid will remain the same, which means the pH will also remain constant.
Muriatic acid is what is used to reduce alkalinity in water.
Yes, the dissolution of sulfuric acid in water is a chemical change because it involves the breaking of ionic bonds in the sulfuric acid molecules as they interact with water molecules to form new chemical species through ionization.
No, you don't ever change battery water. Batteries have hydrochloric acid in them, not water, even though you use water to top them off. Do not mess with the acid in your battery. You should always use distilled water to fill your batteries.
Yes, water can dilute vinegar and change its pH level slightly. Adding water to vinegar will decrease its acidity, thus raising the pH level. However, the change may be minimal depending on the amount of water added.
