Answer:
.2 M
Explanation:
grams/molar mass=ans./volume(L)=molarity
5.6/56=ans./.500=.2 M
- Hope that helps! Please let me know if you need further explanation.
- Acids are substances that form H^+ ions when dissolved in water.
- Bases are substances that form OH^- ions when dissolved in water.
- Substances with a Low pH ( < 7) have more H^+ ions are classified as Acids.
- Substances with a Higher pH ( > 7) have more OH^- ions and are classified as Bases.
The pH of a solution/substance is a measure of the molar concentration of hydrogen ions in solution/substance and as such, is a measure of the Acidity or Basicity of the solution/substance.
The letters pH stands for " Power of Hydrogen." and the:
Numerical Value: is defined as the Negative Base 10 Logarithm of the Molar Concentration of Hydrogen Ions.
pH = log10[ H^+]
Hope this Helps!!!!
Answer:
3.56
Explanation:
pH refers to a measure of hydrogen ion concentration. It measures acidity or alkalinity of a solution. It usually ranges from 0 to 14.
If pH of aqueous solutions at 25°C is less than 7 then they are acidic, while aqueous solutions with a pH greater than 7 are alkaline.
Concentration of hydroxide ions = 
pH = 
pOH = 14 - pH = 14 - 10.44 = 3.56
