How many milliliters of a 3.00 M solution of hydrochloric acid are needed to completely react with 25.0 g of zinc sulfide according to the chemical reaction shown below?
To determine the volume of the 3.00 M solution needed to react with 25.0 g of zinc sulfide, you first need to balance the chemical equation for the reaction. Then, calculate the moles of zinc sulfide using its molar mass. Finally, use the mole ratio from the balanced equation to determine the moles of hydrochloric acid needed, and then use the molarity to find the volume in milliliters.
Determination the concentration of concentrated hydrochloric acid?
To determine the concentration of concentrated hydrochloric acid, you can perform a titration with a standardized solution of a base, such as sodium hydroxide. By carefully adding the base to the acid solution and monitoring the pH change using a pH indicator or a pH meter, you can identify the equivalence point and calculate the concentration of the acid using the volume and molarity of the base solution used in the titration.
Why need to standardize hydrochloric solution?
Standardizing hydrochloric solution is necessary to accurately determine its concentration. By reacting a known quantity of the solution with a standardized solution of a base, the exact concentration of the hydrochloric acid can be calculated. This is important for ensuring the accuracy and reliability of experiments and analyses that require precise concentrations of hydrochloric acid.
How do you know if an acid is concentrated or dilute?
You can determine if an acid is concentrated or dilute by looking at its molarity. A high molarity indicates a concentrated acid, while a low molarity indicates a dilute acid. Additionally, concentrated acids are usually labeled as such on their packaging.
Does hydrochloric acid affect diamond?
No, hydrochloric acid does not react with diamond. Diamond is a very stable and inert substance, and it requires extreme conditions such as high temperature and pressure to chemically react with other substances.
How do you determine the concentration of concentrated hydrochloric acid?
Method: titration with a standardized solution of sodium (or potassium) hydroxide.
How can you determine the strength of hydrochloric acid?
If you know for certain it's hydrochloric acid and nothing else, you could take the pH and determine the concentration from that.

What is percent error calculation used to determine?
It is used to determine how accurate an experimental value is.
Does manual calculation let you determine when Excel calculates formula result?
Yes it does.

How many 12ounce cans will 8ml fill?
To determine how many 12-ounce cans can be filled with 8 milliliters, we first convert 12 ounces to milliliters. There are approximately 29.57 milliliters in one ounce, so 12 ounces is about 355 milliliters. Dividing 8 milliliters by 355 milliliters shows that 8 milliliters is far less than one can, meaning it will not fill even one 12-ounce can.

How do you know if an acid is concentrated or dilute?
You can determine if an acid is concentrated or dilute by looking at its molarity. A high molarity indicates a concentrated acid, while a low molarity indicates a dilute acid. Additionally, concentrated acids are usually labeled as such on their packaging.
What is the normality of commercial grade HCl?
The normality of commercial grade hydrochloric acid (HCl) can vary depending on the concentration specified by the manufacturer. Hydrochloric acid is commonly available in different concentrations, such as 37% or concentrated hydrochloric acid. To determine the normality, it is essential to know the molarity (moles of solute per liter of solution) and the number of equivalents of the acid. Normality (N) is related to molarity (M) by the equation: � = � × � N=n×M where: � N is the normality, � n is the number of equivalents, � M is the molarity. For hydrochloric acid (HCl), which is a monoprotic acid (donates one proton), the number of equivalents ( � n) is equal to 1. Therefore, if you know the molarity of the commercial grade hydrochloric acid, you can determine its normality using the equation mentioned above. It's important to check the product label or contact the manufacturer for the specific concentration of the hydrochloric acid you are using.
