firstly, take 1ml of sodium silicate and add 99ml of water. titrate it with 0.5N HCl and use 1 drop phenophthalein as indicator. the amount of HCl used is converted to gram by using the density and molecular weight calculations.
1.177gm of HCl used for 1 gm of sodium oxide, calculate by multiplying your HCl used for your sodium oxide.
now take 10ml of silicate and weigh it in grams and heat it at 180 degrees celsius for 2 hours to get solid content (water evaporated)
deduct the value of sodium oxide from total solid content obtained.
this is the value of silica in your sodium silicate.

How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
Is amethyst a silicate or non silicate?
Silicate. It is silica, SiO2 with contaminants such as Fe3+ that give it color. technically it is a tectosilicate.
Explain how the silica content of molten material affects the color of igneous rocks?
Silica in molten material tends to crystallise as quartz, which is white or mostly pale in colour. So felsic rocks (from silica-rich magma) tend to be pale, while mafic rocks (from silica-poor magma) tend to be dark in colour.
Is chalcedony silicate or nonsilicate?
Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silicate minerals.
How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
Why is a silicate a silicate?
A silicate is a mineral which contains the element silica.
Why does more silica make lava flow slow?
In rocks lava with a high silica content the silica starts to form a covalent network, where the silicate groups continously bond together.
Are dark colored igneous rocks low in silicate minerals?
They are not low in silicate minerals. They are still primarily composed of them. However, the amount of silica in them is lower than in the lighter-colored rocks. The lightest igneous rocks (felsic) are at least 70% silica while the dark ones (mafic) are between 45% and 52% silica. Silica content below 45% is deemed ultramafic.
What properties of magma help determine the type of eruption?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
Is amethyst a silicate or non silicate?
Silicate. It is silica, SiO2 with contaminants such as Fe3+ that give it color. technically it is a tectosilicate.
What does silica content?
Any metrial or thing which containts silica in it is call silica content..
How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
Explain how the silica content of molten material affects the color of igneous rocks?

What does silica content mean?
Any metrial or thing which containts silica in it is call silica content..
Is zeolite an example of silicate?
silica is used to manufacture zeolite
