What else can I help you with?
What are the solvent and solute in a sloution containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
How do you make 70 ethanol from 190 proof?
To make 70% ethanol from 190 proof ethanol, you can mix 3 parts of the 190 proof ethanol with 7 parts of water. Measure the appropriate volumes of each and combine them in a container, then mix thoroughly to achieve a final concentration of 70% ethanol.
What colour will sodium chloride turn when dissolved in ethanol water and chloroform?
Sodium chloride will not change color when dissolved in ethanol, water, or chloroform. It will form a clear solution in each solvent because NaCl is a colorless salt that does not have any inherent color.
Is ethanol a strong acid?
Ethanol is not a strong acid; it is a weak acid. When ethanol is dissolved in water, it can donate a proton to water molecules resulting in the formation of ethoxide ions. However, ethanol's acidic nature is much weaker compared to strong acids like hydrochloric acid.
What is the antibacterial effect of isopropanol and ethanol?
Isopropanol and ethanol have antibacterial effects by disrupting the cell membranes of bacteria, leading to their destruction.
Will ethanol dissolve polypropylene?
Polypropylene is not dissolved in ethanol.
Why do you use 70 percent alcohol and not 90 percent while microbial culture?
Ethanol creates pores in the cell membrane of the microbial cell by solubilizing the lipoproteins of the membrane. The activity of ethanol determines its concentration. If we 90 percent ethanol, the amount of ethanol molecules available to act upon the cell is more and it attacks the cell membrane from all sides. The dissolved lipoprotein forms a kind of layer around the cell, due to which the alcohol is unable to act further and cause damage to the cell. However, if we use 70 percent ethanol, the amount of ethanol molecules are few and it is not able to attack the cell from all sides. Thus, pores are created intermittently in the plasma membrane, the ethanol penetrates the cell and damages it completely. So, 70 percent ethanol is preferable to 90 percent when using microbial cultures.
Can cooking oil dissolve in ethanol hot?
Cooking oil is dissolved in hot ethanol.
Why did toxic buildup of ethanol inside the cell caused the yeast cell to die?
It denatures proteins and forms miscellular structures attaching to lipids. This about the concentrations though. If they can stand 15% ethanol that's 1 part ethanol for every 5 parts water, roughly. That's a lot.
What temperature does iodine dissolve in alcohol?
Iodine is dissolved in ethanol at any temperature.
How would I answer this question How many grams to 0.1 g of ethanol should be dissolved into 135 g of water to produce a 23 percent by mass ethanol solution?
The answer is 31,05 g ethanol.
How much piperine dissolved in1ml ethanol?
The solubility of piperine in ethanol is about 26 mg/mL. This means that in 1 mL of ethanol, you can dissolve up to 26 mg of piperine.
How would separate salt and sugar?
Sugar is soluble in ethanol; sodium chloride is not dissolved.
How would you separate sugar and salt?
