9 test method for water acid and alkali
GCSE CHEMISTRYWhat is pH How does Universal
Any acid will have a pH of less than 7. Any alkali will have a pH of more than 7. Strong acids (HCl or H 2 SO 4 or HNO 3) have a pH of 1 (red). Weak acids have a pH of 3 to 4 (orange). Examples of weak acids are ethanoic acid citric acid (lemon juice) and rain water. Rain water has a natural pH of 5·5 (see carbonic acid). Water and salts are
