What else can I help you with?
Is dilution is the addition of solute to decrease the concentration of solvent?
No. dilution is the addition of solvent to decrease the concentration of a solute.
Autonomic nervous system does the addition of epinephrien imitate?
The autonomic nervous system responds to the addition of epinephrine by causing an increase in heart rate, blood pressure, and blood flow to muscles. This is part of the "fight or flight" response, where the body prepares for intense physical activity or stress.
What happens to polypeptide chains after translation?
In bacteria, translation occurs in the cell's cytoplasm, where the large and small protein production is addition of one amino acid at a time to the end of a protein.
What is the purpose of potassium hydroxide pellet in this experiment?
it combines with the CO2 and creates an insoluable precipatent.
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
How does the addition of ADH affect the concentration of potassium in the urine?
Anti-diuretic hormone (ADH) causes water to be absorbed from the urine back into the body. Everything else in the urine, including electrolytes such as potassium, is concentrated.
What effect would it have on the value of the concentration of sodium hydroxide if the conical flask contains some distilled water before the addition of potassium hydrogenphthalate?
the conentration will be increased.
Is dilution is the addition of solute to decrease the concentration of solvent?
No. dilution is the addition of solvent to decrease the concentration of a solute.
What would cause addition of KCN to water?
When potassium cyanide (KCN) is added to water, it dissociates into potassium ions (K+) and cyanide ions (CN-). These ions can then react with water molecules to form stable complexes, such as potassium cyanide ion or hydrocyanic acid, depending on the concentration and pH of the solution. This reaction releases cyanide ions, which can be highly toxic.
Is Surface tension of water affected by potassium permanganate?
Potassium permanganate can potentially alter the surface tension of water, as it is a strong oxidizing agent. When added to water, it can break down organic compounds and reduce the surface tension. However, the effect may vary depending on the concentration of potassium permanganate and other factors.
Does the pH of the solution increase decrease or stay the same when you add solid potassium chloride to dilute solution of potassium hydroxide?
The pH of the solution will decrease when solid potassium chloride is added to a dilute solution of potassium hydroxide. This is because potassium chloride is a neutral salt that will not affect the pH significantly, while potassium hydroxide is a strong base. The addition of more chloride ions will reduce the concentration of hydroxide ions in the solution, leading to a decrease in pH.
Graph of conductomertic titration of silvernitrate with potassium chloride?
The reaction between silvernitrate and potassium chloride during titration produces silver chloride which exist as solid(precipitate) and potassium nitrate an aqueous solution. Since the number/ concentration of freely moving ions in the resulting mixture is decreasing the electrical conductivity of the resulting mixture will decrease. Once the reaction is complete, the electrical conductivity will be minimum because at this stage only the freely moving ions in the potassium nitare able to conduct electric. Further addition of silver nitrate into the resulting mixture increases the concentration of freely moving ions hence increasing the electrical conductivity. The graph in V shape form
How does the sodium potassium pump operates?
The sodium-potassium pump functions much like a revolving door. Its main job is to keep sodium ions (NA+) outside of the cell and keep potassium ions (K+) inside of the cell. With the addition of energy from an ATP molecule, the sodium potassium pump moves three sodium ions out of the cell and moves two potassium ions into the cell with each turn. The goal of this process is to return, or keep, the cell at a resting state, or resting potential.
Does magnesium and potassium hydroxide cause a reaction?
With the addition of certain catalysts and heat, yes. Be careful.
What salt do you get by mixing nitric acid and potassium hydroxide?
The reaction between nitric acid and potassium hydroxide will yield potassium nitrate (KNO3) in addition to water. Potassium nitrate is a colorless, crystalline salt that is commonly used in fertilizers, food preservation, and fireworks.
How do you prepare 0.02 m phosphate buffer?
To prepare a 0.02 M phosphate buffer, you would need to mix suitable amounts of a monobasic potassium phosphate and a dibasic potassium phosphate solution with water to achieve the desired concentration. Calculate the required volumes of each solution based on their respective concentrations and molar masses. Finally, adjust the pH as needed with the addition of acid or base.
What is the change in conductivity as the concentration of the NaCl solution was increased by the addition of NaCl drops?
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
