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 typically light in color with a higher silica content, while gabbro is dark in color with a lower silica content. This difference in silica content results in contrasting mineral compositions and textures between the two rocks.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
How do silica tetrahedra bond in silicate minerals?
Silica tetrahedra in silicate minerals are linked together by sharing oxygen ions at the corners of the tetrahedra. This creates a strong network structure known as a silicate framework that gives the mineral its physical and chemical properties. The arrangement and bonding of these tetrahedra determine the crystal structure and properties of the silicate mineral.
How can color help determine the silica content of an igneous rock?
Color can provide a rough indication of the silica content in igneous rocks; rocks with higher silica content tend to be lighter in color (e.g. pink, white), while low-silica rocks are darker (e.g. green, black). However, color alone is not a definitive way to determine silica content as other factors like mineral composition can also influence the overall color of the rock. Geochemical analysis through techniques such as X-ray fluorescence or electron microprobe analysis is more accurate for determining silica content in igneous rocks.

Why is a silicate a silicate?
A silicate is a mineral which contains the element silica.

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.

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.
Is zeolite an example of silicate?
silica is used to manufacture zeolite
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.
