How would you differentiate between dioctahedral and trioctahedral clay minerals?
The trioctahedral sheet silicates where each O or OH ion is surrounded by 3 divalent cations, like Mg+2 or Fe+2. The dioctahedral sheet silicates where each O or OH ion is surrounded by 2 trivalent cations, usually Al+3.
What does Spheration mean?
Definition of spheration : the act or process of taking the form of a sphere.
What does QUTH mean?

What is Dioctahedral and Trioctahedral?
The key difference between dioctahedral and trioctahedral is that dioctahedral refers to having two of the three available octahedrally coordinated positions occupied, whereas trioctahedral refers to having all three available octahedrally coordinated positions occupied.
What is Dioctahedral sheet?
When only two octahedral sites filled with trivalent cations is a dioctahedral sheet. When magnesium with a positive charge of two (Mg+2) is present, all three positions are filled by divalent cations is a trioctahedral sheet . Cite.
How does reverse Spherification work?
When you pour a spoonful of the flavorful liquid into the spherification bath, the liquid draws itself into a nearly spherical shape. As the sphere sinks, calcium ions at its surface cause a membrane of alginate to gel, encapsulating the sphere of flavorful liquid. So why is it called reverse spherification?
