Does the melting rate depend on the amount of solute added?
Yes, adding a solute to a solvent can affect the melting rate. When a solute is added, it disrupts the crystal lattice structure of the solvent, which can either increase or decrease the melting rate depending on the specific solute-solvent interaction. Generally, adding a solute lowers the melting point of the solvent and can lead to a faster melting rate.
How do you prove that glucose do not raise the melting point of stearic acid?
To prove that glucose does not raise the melting point of stearic acid, conduct a melting point analysis of stearic acid alone and stearic acid mixed with glucose. If the melting point of the mixture is the same as that of stearic acid alone, it indicates that the presence of glucose does not affect the melting point of stearic acid. This experiment can help demonstrate that glucose does not raise the melting point of stearic acid.
What is the trend in melting point and boiling points of the elemets in group 1 and 7?
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
What is the melting point for Mg?
The melting point of magnesium is 650 degrees celcius. It has the lowest melting point among all the group II metals (alkaline earth metals), though the melting points generally decrease down the group - magnesium is an exception and has the lowest melting point among them.
How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
Why KCl or KF is added in the electrolysis of molten NaCl?
To decrease melting point of NaCl
Where does the salt in ice cream go?
Ice is added to decrease the melting point of ice cream.
When common salt is added to ice than what is its melting point?
The freezing point is lowered; the decrease is proportional to the content of salt.
How do minerals affect a rock's melting point?
Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.
When pressure on a piece ice is increased its melting point will be?
When pressure on a piece of ice is increased, its melting point will decrease. This is because an increase in pressure will stabilize the solid phase, making it harder for the ice to melt into liquid water.
What Would be the effect poorly packed in melting point?
The effect of poorly packed will decrease the melting point.
How can liquid be turned into a solid?
the solid must reach its melting point which varies with every substance
What will happen to the melting point of ice if some common salt is added to it?
The melting point is lowered.
Does melting point depend on atmospheric pressure?
Yes, the melting point of a substance can be influenced by atmospheric pressure. In general, an increase in pressure raises the melting point of a substance, while a decrease in pressure lowers it. This is because pressure affects the equilibrium between the solid and liquid phases.
How you can down the melting point of palm stearin?
Increasing the purity of most substances increases the melting point. The opposite is also true: decreasing purity usually results in a decrease in melting point. Adding another palm oil derivative or palm oil itself would decrease the melting point of the palm stearin.
Does salt increase the melting point?
Yes......
