Is sio2 more acidic than so2?
When dissolving CO2 in water it forms a weak acid: H2CO3. SiO2 will not dissolve in water, so it is not acidic (nor base)
What is the differences between calcite and quartz?
Calcite is the opaque compound calcium carbonate (CaCO3). It will dissolve in carbonic acid and will fizz in stronger acids. Quartz is the usually transparent compound silicon dioxide (SiO2). It will not dissolve in acid.
Will quartz dissolve in acid?
Quartz will only dissolve in hydroflluoric acid.
Which acids dissolve copper?
16Mtric acid will dissolve copper, without heating.
Will something dissolve faster in an acid or base?
An acid will dissolve something faster.

A strong acid completely dissolve into ions when mixed with water. A weak acid only partially dissolve.
Can stomach acid dissolve a penny?
yes, the acid in your stomach can Evan dissolve a one pound coin.
How do you separate zinc phosphate and SiO2 also known as sand?
Neither compound is soluble in water, however zinc phosphate will dissolve in acids while silicon dioxide will not, except for hydrofluoric acid. The reaction of zinc phosphate and the common acid hydrochloric acid is: Zn3(PO4)2 + 6 HCl -----> 3 Zn+2 (aq) + 6 Cl- (aq) + 2 H3PO4 (aq).All of the products from the reaction of zinc phosphate with hydrochloric acid are soluble in water. Therefore, the mixture of zinc phosphate and SiO2 only needs to be mixed with hydrochloric acid, stirred for 5 or 10 minutes and the liquid decanted off. To purify the remaining SiO2, it needs to be washed 3 to 5 times with pure water.

What is a weak acid Apex?
