What is the pH of 0.05 M of HCl?
The pH of a 0.05 M solution of hydrochloric acid (HCl) can be calculated using the formula pH = -log[H⁺]. Since HCl is a strong acid that dissociates completely in water, the concentration of hydrogen ions [H⁺] is equal to the concentration of the acid, which is 0.05 M. Therefore, the pH is approximately 1.30.
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
Why did bicarbonate have an effect on pH when you mixed it with water?
Sodium bicarbonate increases the pH of water.
What is the effect of decreasing the temperature of the pH of water?
Decreasing the temperature of water the value of pH increase.
How do you prepare 0.1M PBS OF pH 7?
To prepare 0.1M PBS of pH 7, mix appropriate amounts of monobasic potassium phosphate, dibasic potassium phosphate, and sodium chloride in distilled water. Adjust the pH with HCl or NaOH as needed. To reach a pH of 7 for a 0.1M PBS, adjust the pH to 7.4 with NaOH or HCl.
What is the pH of water after adding HCl and calculating the resulting pH level?
The pH of water decreases after adding HCl due to the increase in hydrogen ions. The resulting pH level depends on the amount of HCl added.
If you add hydrochloric acid (HCl) to water what effect would this have on the H plus ion concentration On the pH?
Adding hydrochloric acid (HCl) to water will increase the H+ ion concentration, leading to a decrease in pH. This is because HCl dissociates in water to form H+ ions and Cl- ions, increasing the concentration of H+ ions in the solution and lowering the pH.
The pH of a 0.01 M solution of HCl in water would be?
The pH of a 0.01 M solution of HCl in water would be approximately 2, since HCl is a strong acid that completely dissociates in water to form H+ ions. This high concentration of H+ ions results in a low pH value.
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
What is the pH of 0.05M of HCl?
The pH of 0.05 M HCl is 1.3. HCl is a strong acid that dissociates completely in water to release H+ ions, resulting in a low 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 )
The pH of 0.005N HCl is?
The pH of a 0.005N HCl solution is approximately 2.3. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, leading to an acidic pH.
What is the pH of .25M HCl?
The pH of a 0.25 M HCl solution is approximately 0.60. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, resulting in a high concentration of H+ ions and a low pH.
What is the pH of a 0.140 M HCl solution?
The pH of a 0.140 M HCl solution is approximately 0.85. This is because HCl is a strong acid that completely dissociates in water to give H+ ions, resulting in a low pH.
What is the affect of hcl on the pH of water?
Hydrochloric acid (HCl) is a strong acid that dissociates completely in water, releasing hydrogen ions (H⁺). This increase in H⁺ concentration lowers the pH of the water, making it more acidic. The extent of the pH change depends on the concentration of HCl added; higher concentrations result in a more significant decrease in pH. For example, a 0.1 M solution of HCl can lower the pH to around 1.0.
What is the pH of 10.0 mL of 0.0020 M HCl?
The pH of a 0.0020 M HCl solution is approximately 2.7. This is because HCl is a strong acid that completely dissociates in water to form H^+ ions, decreasing the pH of the solution.
What is the pH of 10.0L of 0.0020 M HCL?
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
