What is the effect of HCl on the pH if water?
Adding hydrogen chloride to water the pH decrease.
The pH of a 0.01 M solution of HCl in water would be?
pH = - log[H+] so a 0.01 M solution of HCl has, pH= 2
What is the concentration of HCl if it makes a solution in water of pH 1.5?
Since pH=-log[H+], then [H+]=10-pH 10-1.5=.0316 And since HCl is a strong monoprotic acid, the [H+]=[HCl] So the concentration is approximately 0.0316M
When HCL is added to water why does the pH level drop so fast?
HCl is an acid. The hydrogen part of the molecule makes it so. A pH below 7 is acidic and a pH above 7 is basic. It makes sense that adding an acid to water would lower the pH.
What is the pH of .25M HCl?
- log(0.25 M HCl) = 0.6 pH ------------
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
Does ozone affect pH?
No, ozone does not affect PH of water. However as ozone is a powerful oxidizer it can oxidize compounds in the water that may indirectly change the PH of the water.
What If enough water is added to 5 g of HCl to make 1 liter of solution what is the pH?
Find moles HCl. 5 g HCl (1 mole HCl/36.450 grams) = 0.1372 moles HCl Now, Molarity = moles of solute/Liters of solution Molarity = 0.1372 moles HCl/1 liter = 0.1372 M HCl Then. -log(0.1372 M HCl) = 0.9 pH ( you might call it 1, but pH can be off the scale ) -----------
Does boiling water affect its pH?
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
How does the presence of HCl affect activity of peroxidase?
The optimum pH for activity of Peroxidase is 5-7 that is about neutral. The Hydrochloric acid reduces the pH and thus inactivates the enzyme with reducing pH.
What is the pH of 260M HCl?
.260 M of HCL, not 260 More than likely correct, but, - log(0.260 M HCl) = 0.6 pH ----------- ( pH can be below 1 )
What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
