Do monosaccharides dissolve in water?
When glucose or other monosaccharides are placed in an aqueous solution, they curl and take a ring form. This is in contrast to the linear form they take otherwise.
Which is strong acid water or phenol?
A strong acid is typically stronger than phenol in terms of acidity due to its ability to fully dissociate in water to release protons. Phenol is a weak acid that only partially dissociates in water, making it less acidic compared to strong acids like hydrochloric acid or sulfuric acid.
Is nitrogen trichloride soluble in water?
Nitrogen trichloride (NCl₃) is only slightly soluble in water. While it can dissolve to some extent, its solubility is limited due to its chemical structure and properties. As a result, it does not form a significant concentration in aqueous solutions.
Is smelling phenol is good or bad?
Smelling phenol is considered harmful, as it can irritate the respiratory system, eyes, and skin. Short-term exposure may lead to symptoms such as headaches, dizziness, and nausea, while long-term exposure can have more serious health effects. It is advisable to avoid inhaling phenol and to use it only in well-ventilated areas or under proper safety precautions. Always consult safety guidelines when handling chemicals like phenol.
What chemicals dissolve cordierite and quartz?
Hydrofluoric acid (HF) is commonly used to dissolve both cordierite and quartz due to its ability to react with silica-based minerals. However, it is important to handle HF with extreme caution as it is highly toxic and corrosive. Other chemicals such as hot concentrated sulfuric acid (H2SO4) can also be used to dissolve these minerals.
Is mgOh aqueous?
Yes, magnesium hydroxide (Mg(OH)2) is sparingly soluble in water, meaning it does dissolve to form an aqueous solution. However, it is only slightly soluble, so not all of it will dissolve completely in water.
Is calcium hydroxide aqueous?
Yes, calcium hydroxide is sparingly soluble in water, so a small portion of it will dissolve to form a saturated solution, making it aqueous.
What amount of NaOH is required to prepare 1N NaOH solution and why only that amount is used?
To prepare a 1N NaOH solution, you would need to dissolve 40 grams of NaOH in water to make 1 liter of solution. This amount is used because 1N solution means 1 mole of NaOH per liter of solution, and the molar mass of NaOH is 40 g/mol, so 40 grams of NaOH is needed to have 1 mole in 1 liter of solution.
Baking Soda mixed with calcium chloride and phenol red solution chemicla or physical change?
It is a chemical change because it produces heat which is evidence that a chemical change has occured.
What acid can dissolve SiO2?
Hydrofluoric acid (HF) is commonly used to dissolve SiO2 (silicon dioxide) due to its ability to react with the silicon in the compound. However, HF is highly corrosive and extremely hazardous, requiring careful handling and special precautions.
Why is it good that lipids in cell membranes do not dissolve in water?
If the phospholipids in your cell membranes were suddenly able to dissolve in water, you would become a thick puddle on the floor. You are basically one big aqueous solution, and the cell membranes are the only thing keeping the cell compartmentalized.
As edta dissolves in water the h will increase to achieve a pH 8.0 would you need to add hcl or naoh?
To achieve a pH of 8.0, you would need to add NaOH (sodium hydroxide) to increase the pH. NaOH is a strong base that will react with water to produce hydroxide ions, which will raise the pH. Adding HCl (hydrochloric acid) would lower the pH as it is a strong acid.
What Chemical equation illustrates the neutralization of sodium hydroxide and hydrochloric acid?
This equation can be written as NaOH (aq) + HCl (aq) -> NaCl (aq) + H2O if the reaction occurs in aqueous solution. The only actual chemical reaction is between the aquated hydroxide and hydrogen ions, the chloride and sodium ions being "spectators" only.
Do monosaccharides dissolve in water?
When glucose or other monosaccharides are placed in an aqueous solution, they curl and take a ring form. This is in contrast to the linear form they take otherwise.
Does phenol give a positive biuret test?
No, phenol does not give a positive biuret test. The biuret test is used to detect the presence of proteins, not phenol. Phenol is a type of organic compound that does not contain the peptide bonds that the biuret test reacts with.
Would NaOH eat through glass?
Yes, but only after an extended period of time, and depending on the concentration. I kept a 500 mL glass jar off 50% NaOH in my lab for two years and the glass didn't dissolve, but did get eaten away. At the bottom of the jar there was a rather thick, but under a cm, layer of residue and you could tell that the NaOH has eaten some of the glass away.
Why is it water requires to be boiled first before add to NaOH?
The water as it was was impure, that is, it contained other impurities such as sulphur and other element. Boiling the water will remove the impurities so that when the water is added to the NaOH, any reaction will be between the water and NaOH only. If the water was not boiled, the impurities in the water could react with the water.
