The pH scale starts at 0 and goes up to 14. Halfway between 0 and 14 is 7, which is neutral. Compounds are acidic if they have a pH lower than 7. Compounds with a pH higher than 7 are said to be basic or alkaline.

WebWorksheet 23 – Strong Acid/Strong Base Titrations A. Initial pH This is always determined based solely on the initial concentration of the acid or base being titrated. Every mole of acid or base will produce one mole of H ... The pH is determined by calculating the number of moles of unreacted acid or base remaining in the solution. WebThe pH scale is a number scale that indicates how acidic or basic a solution is. Acids have a pH below 7 and bases have a pH above 7. Neutral solutions have a pH of 7. On the pH …
WebThe scale is centered around the pH value of 7. A pH value of less than 7 indicates an acidic solution. A pH of 7 indicates that a solution is neutral. A pH value of greater than 7 indicates a basic solution. Acidic pH < 7. Neutral pH - 7.0, Basic pH > 7 Chemical compounds that change color in the presence of certain ions are called Indicators.
