WebCalculate pH of following HCl solution. Data of concentrated HCl is given below. density = 1.18 g cm -3 HCl w/w% = 36.5 From unit conversion, density = 1180 g dm -3 Because volume is not given, we can take volume as 1 dm 3. As the next step, find the mass of that solution (1 dm 3 ). Mass of HCl solution = 1180 g Now, mass of HCl in 1 dm 3 is found.

Webbetween 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. Later, however, in locations down river, the pH began to return to pre-incident levels.
WebDec 24, 2024 · For example, orange juice would have a pH of 2 because it is quite acidic. In contrast, bleach has a pH of 12 as it is quite basic. Numbers in the middle of the scale are neutral, such as water, with a pH of 7. One level of pH is a 10x difference. For example, when comparing pH 7 to pH 6, pH 6 is ten times more acidic than pH 7.
