Is the Combined Solution Acidic or Basic?

  • Thread starter Zoey Brown
  • Start date
In summary, the student has 250ml of 1.5M HCl and 150ml solution of 2.0M Ba(OH)2. The combined solution will be acidic since both HCl and Ba(OH)2 are acidic reactants. The limiting reactant is Ba(OH)2, which means BaCl2 will also be present in a 1:1 mole ratio. To determine the excess reactant, the quantities should be converted to moles and compared using ratios based on the written reaction.

Homework Statement


A student has 250ml of 1.5M HCl and 150ml solution of 2.0M Ba(OH)2. When he mixes the 2 together, is the combined solution acidic or basic?

Homework Equations


n=cv
ph=-log[h]

The Attempt at a Solution


the limiting reactant is Ba(OH)2. it is .3 moles which means bacl2 will also be .3 moles

Which reactant is in excess?

Change each quantity to moles. Write the reaction. Use ratios according to the written reaction and compare to the moles you started for each reactant.

H'm yes, but moles of what? When he writes the reaction as you suggest he may well see that it's not the moles of "Ba(OH)2 or of Ba that most matter. :oldwink:

BOTH of them
 

What is the difference between acidic and basic products?

Acidic products have a pH level below 7, while basic products have a pH level above 7. This means that acidic products have a higher concentration of hydrogen ions, while basic products have a higher concentration of hydroxide ions.

How can I tell if a product is acidic or basic?

You can use pH test strips or a pH meter to determine the acidity or basicity of a product. Alternatively, you can look for key words on the product label, such as "acidic" or "basic", or check the ingredients list for acidic or basic compounds.

What are some examples of acidic products?

Some examples of acidic products include vinegar, lemon juice, battery acid, and soda. These products have a pH level below 7 and are often used for cleaning, cooking, or as industrial chemicals.

What are some examples of basic products?

Some examples of basic products include baking soda, bleach, ammonia, and soap. These products have a pH level above 7 and are often used for cleaning, personal hygiene, or as industrial chemicals.

Can acidic or basic products be harmful to my health?

Yes, acidic or basic products can be harmful to your health if not used properly. Strong acids and bases can cause chemical burns on the skin and damage to internal organs if ingested. It is important to always read and follow the instructions on product labels and use caution when handling acidic or basic products.
