No because the marble was just added to make the water level rise
Just add water!
No it is a heterogeneous mixture, I believe
The color will be a fairly strong red as it is a very strong acid in the pH scale.
If your battery is not a sealed unit you add pure distilled water.
Normally, you only add distilled water.
when batteries are new never use mixture water but when batteries become old and weak then you need to add mixture water
you add some water to the mixture :D

Marble is a homogeneous mixture. It is composed primarily of the mineral calcite, along with other minerals like quartz and mica, all mixed together in a uniform manner. It is not a pure substance since it is made up of multiple components.
Just like granite, marble is a mixture. However, unlike granite, marble is typically more than 90% calcium carbonate, so it might count as a pure substance. Marble is a type of limestone, so is a mixture.
add water so they dissolve
You would not add sand to a mixture intended as a lubricant.
