A Salt Or Ester Of Sulphuric Acid
The solubility of Group 1 sulphates generally increases down the group, as the ionic size increases, leading to weaker ionic bonding. In contrast, the solubility of Group 2 sulphates decreases as you move down the group due to the increased lattice energy resulting from higher charge density and stronger ionic bonding.
Yes, Tresemme shampoo does contain sulphates, although their Naturals collection has a low-sulphate shampoo in the range.
Sulphates are usually soluble in water except for Ag2SO4, BaSO4, CaSO4 and PbSO4 (lead sulphate). Hope that helps (: PbSO4 is sparingly soluble in water, its solubility at 298K is about 1.4E-4 mol/L, a very small value. So its not insoluble, it just has a very small solubility. Most sulphates of group 2 elements have low solubilities with the solubilities decreasing down the group, so that the sulphates of the top 2 elements, Be and Mg are reasonably soluble, then the solubilities decreasing for Ca, Sr and Ba. Other elements with very low solubilities for sulphates include Sb (antimony), Hg (mercury, Ag (silver) and Pb (lead). The solubility of lead sulphate can apparently be increased by additio0n of acid or ammonia or both (or ammonium salts).
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
Sulfides are insoluble unless combined with Li, Na, K, Rb, Cs, and NH4. So, Na2S is soluble, and CuS is insoluble.
Substances which are reacted with Sulphuric acid tend to produce sulphates.

Sulphates can affect people, particularly those who are sensitive or allergic to them. They may experience symptoms like skin irritation, respiratory issues, or digestive problems when exposed to sulphates in certain products such as cosmetics, medications, or food additives. It's important for individuals with sensitivities to avoid products containing sulphates and consult a healthcare professional if needed.
Hydrochloric acid (HCl) is used in the limit test of sulphates because it helps in the precipitation of sulphates as insoluble barium sulphate (BaSO4). This makes it easier to quantitatively determine the amount of sulphate present in a sample through gravimetric analysis. The addition of excess HCl ensures that all sulphates are converted to BaSO4, allowing for accurate measurement.
Acetic acid is added in the limit test for sulphates to prevent the precipitation of other metal ions that could interfere with the test results. It forms a soluble complex with various metal ions, ensuring that only sulphates are precipitated and measured accurately.

Sulphates, phosphates, oxides, halides and carbonates are minerals that do not contain silicon.
