Ph value of 4
WebJul 21, 2024 · Find the pH if the H + concentration is 0.0001 moles per liter. Here it helps to rewrite the concentration using scientific notation as 1.0 x 10 -4 M. This makes the formula: pH = - (-4) = 4. Or, you could just use a calculator to take the log. This gives you: Answer: pH = – log (0.0001) = 4 Calculate the pH of a Strong Acid Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm , has a pH of 14. Thus, measure…

Webgenerally, pH levels were measured before the arrival of the contaminant plume and found to range between 6.5 and 7.6. When the contaminated water from the mine release passed a sampling location, the pH lowered (indicating more acid) to approximately 4.8 (below Silverton). A pH of 4.5 is consistent with the pH of a liquid like black coffee. WebAug 31, 2024 · A neutral pH is 7.0. The average urine sample tests at about 6.0, but typical urine pH may range from 4.5–8.0.
