What kind of precipitate is formed when alcohol is added to denatured DNA?
When alcohol is added to denatured DNA, a white stringy precipitate of DNA will form. The DNA precipitates out of the solution because of its insolubility in alcohol, allowing it to be separated from the rest of the solution.
Why is alcohol added the DNA solution?
Alcohol is added to the DNA solution to help precipitate the DNA out of the solution. This allows the DNA to be separated from other cellular components such as proteins and lipids. The DNA can then be collected and further analyzed or used in experiments.
How does the concentration change as solid solute drink mix is added?
The concentration increases as solid solute drink mix is added to a solvent (such as water) because more solute particles are being added to the same volume of solution. The concentration is directly proportional to the amount of solute per unit volume of solution.
What is result by adding water to alcohol?
When water is added to alcohol, it lowers the overall alcohol content of the mixture. This process is known as dilution and results in a beverage with a lower alcohol percentage than the original alcohol content.
How much 80 percent alcohol added solution must be added to 7 liters of 60 percent alcohol to make sure a mixture of 73 percent?
80x + 60*7 = 73*(x+7) so x = 91/7 = 13 L (of 80% alc)Added noteto deal with the so called 'dilution contraction' of total volumeIf it were % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law). You calculate with mass (kg) and mass-% (%m/m) i.s.o. volume (L) and vol% (%v/v).However if the meaning was: % by Volume ( %v/v) then calculation appears to become quite complicated, but not impossible if you know at least the density values of all solutions (original 80%v/v or 60%v/v and final 73%v/v).DO NOT use: (orig. volume) + (added volume) = final volume, as done above, if exact figures are necessary.It's only a rule of thump, an approximation. This is because fluids can contract on mixing at dilution. There is no rule such as: conservation of volume.Your case: 13 L + 7 L (is not equal but) < 20 L final solution.
What is the percentage of volume if 25 ml methyl alcohol if 25 added to make 50 ml solution?
To find the percentage volume of methyl alcohol in the solution, you can use the formula: [ \text{Percentage Volume} = \left( \frac{\text{Volume of solute}}{\text{Total volume of solution}} \right) \times 100 ] In this case, the volume of methyl alcohol is 25 ml and the total volume of the solution is 50 ml. Thus, the percentage volume is: [ \left( \frac{25 , \text{ml}}{50 , \text{ml}} \right) \times 100 = 50% ] So, the percentage of volume of methyl alcohol in the solution is 50%.
What kind of precipitate is formed when alcohol is added to denatured DNA?
When alcohol is added to denatured DNA, a white stringy precipitate of DNA will form. The DNA precipitates out of the solution because of its insolubility in alcohol, allowing it to be separated from the rest of the solution.
How much pure alcohol must be added to 7 liters of 10 percent alcohol solution to increase the concentration to 30 percent alcohol?
2 litersLet X represent the amount of pure alcohol to be added to the 7 liters of 10% alcohol solution to get a 30% alcohol solution. We want .3(7+x)=.1*7+x [because we need the alcohol in the final solution to equal the amount of alcohol in the original solution plus the amount of alcohol we are adding). Solving for x, we get:.3(7+x)=.1*7+x2.1+.3x=.7+x1.4=.7x2=xThus, 2 liters of pure alcohol needs to be added to the solution.Added noteto deal with the so called 'dilution contraction' of total volumeIf it were % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law).

Why is alcohol added the DNA solution?
Alcohol is added to the DNA solution to help precipitate the DNA out of the solution. This allows the DNA to be separated from other cellular components such as proteins and lipids. The DNA can then be collected and further analyzed or used in experiments.
What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?
The final percent concentration of the solution would be approximately 12.0% methanol. This is calculated by dividing the volume of methanol by the total volume of the solution (600 ml / 5000 ml) and then multiplying by 100 to get the percentage.
What is fotifiwd wines?
Wines with high-alcohol, grape distillate added to it.
When the solution is diluted the volume will be more?
When a solution is diluted, additional solvent is added, which increases the total volume of the solution. This dilution process reduces the concentration of the solute in the solution while keeping the amount of solute constant.
What happens to a concentrated solution when a large amount of solventis added to it?
When a large amount of solvent is added to a concentrated solution, the concentration of the solution decreases. This process is known as dilution. The overall volume of the solution increases, but the amount of solute remains the same.
How much water must be added to 12 L of a 40 percent solution of alcohol to obtain a 30 percent solution?
4 litres
How does the concentration change as solid solute drink mix is added?
