Is a 0.1M solution of NaNO2 acidic or basic?
A 0.1M solution of NaNO2 is acidic. Sodium nitrite (NaNO2) is a salt composed of a weak acid (nitrous acid) and a strong base (sodium hydroxide). The nitrite ion hydrolyzes in water to produce nitrous acid and hydroxide ions, which makes the solution acidic.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
Colors of sodium hydroxide in phenolphthalein?
Sodium hydroxide in phenolphthalein solution appears as a bright pink color when the solution is basic due to the presence of hydroxide ions. Conversely, in neutral or acidic solutions, the color fades to become colorless.
Is sodium peroxide a basic or acidic oxide?
Sodium peroxide is a basic oxide because it reacts with water to form a basic solution containing sodium hydroxide.
What is the color of sodium hydroxide solution?
none, it is clear
Why is sodium hydroxide not used in acidic rains?
Sodium hydroxide is a dangerously strong base that can be just as damaging as a strong acid. Even a small error in measurement can make a solution too basic
Is sodium hydroxide solution neutral?
No. A sodium hydroxide solution is very basic.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
Is salt solution a acid alkali or neutral?
A salt solution can be acidic, basic, or neutral depending on the cation and anion present in the salt. For example, a solution of sodium chloride (NaCl) is neutral, while a solution of ammonium chloride (NH4Cl) is acidic and a solution of sodium hydroxide (NaOH) is basic.
Is the solution of sodium nitrite acidic or basic?
Sodium nitrite is a basic compound. When dissolved in water, it forms a solution that is slightly basic due to the presence of the nitrite ion, which can accept protons and increase the concentration of hydroxide ions.
How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
What happens when methyl orange is added to sodium hydroxide?
When methyl orange is added to sodium hydroxide, the color of the solution changes from red (acidic) to yellow (basic). This indicates that the solution has become more alkaline due to the reaction between the sodium hydroxide and the indicator. Methyl orange is an acid-base indicator that changes color based on the pH of the solution.
