Why is slaked lime added to water after chlorination?
Slaked lime is added to water after chlorination as a coagulant to destabilize the electrostatic charges of suspended particles in the water.
What is the 'neutralising value' of lime?
This is a measure of the effectiveness of agricultural lime at neutralizing soil. It takes into account the mesh size of the particles (if they are too big they don't work) and the purity of the limestone.
Why does lime water go cloudy?
Lime water goes cloudy when a reaction takes place with carbon dioxide. Lime water detects the presence of lime water.
Which describes breccia?
A. a clastic sedimentary rock with angular particles B. a chemical sedimentary rock C. a biochemical sedimentary rock D. a clastic sedimentary rock with large, rounded particles answer is a
Which agent of erosion deposits irregular mounds of unsorted sediment with parallel scratches on rounded particles?
It is produced by the movement of a glacier
What is wind-worn particles?
They are sedimentary particles that have been rounded and reduced in size due to abrasion with other airborn particles.
Why is slaked lime added to water after chlorination?
Slaked lime is added to water after chlorination as a coagulant to destabilize the electrostatic charges of suspended particles in the water.
What is the difference between slaked lime and lime water?
When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.
What is the 'neutralising value' of lime?
This is a measure of the effectiveness of agricultural lime at neutralizing soil. It takes into account the mesh size of the particles (if they are too big they don't work) and the purity of the limestone.
What is known as the milk of lime?
When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime. Milk of lime is an alkaline solution with a pH of 12.3.
Why does lime water go cloudy?
Lime water goes cloudy when a reaction takes place with carbon dioxide. Lime water detects the presence of lime water.
What is axle grease made from?
axle grease is a lubricating grease containing suspended lime particles and thickened with rosin soap.----
How coarse aggregate shape affect workability?
Aggregates with angular particles are more difficulties to compact than one with rounded particles and therefor,requires more water in the mix to act as alubricant.this additional water, on evaporation ,tends to leave void spaces in the hardened concrete made with rounded aggregates particles which requires less water for compaction.the nature of the particles of an aggregates will also affect workability.(
What does attrition mean in geography?
Attrition: The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size.
Which describes breccia?
A. a clastic sedimentary rock with angular particles B. a chemical sedimentary rock C. a biochemical sedimentary rock D. a clastic sedimentary rock with large, rounded particles answer is a
What processes create a rounded and smooth rock?
== == Weathering and erosion. Weathering causes rock to break into smaller particles. When these particles are transported by wind, water, or ice, the jagged edges from fracture are gradually worn down from abrasion with other particles, making the outer surface appear relatively smooth. Sometimes the mere abrasive effects of windblown particles on a rock will smooth the exposed surface, leaving the remainder of the rock jagged. Rounded and smoothed stones, if rounded and smoothed on all sides, are usually the product of tumbling. Tumbling is usually accomplished by transportation of the stone by water and contact with other rocks. == ==
What is milk of lime?
the milk of lime is... wait for this... the lime of milk. ================================================================== Kidding aside from the first answer, milk of lime is another common name for limewater, a saturated solution of calcium hydroxide. It got its name from the process of its preparation, wherein excess calcium hydroxide is stirred in pure water and filtering off the excess insoluble Ca(OH)2. When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime.
