PPT-Week 6 – Acids and Alkalis

1 Indicators and the pH scale Solutions can be acidic alkaline or neutral we get an  acidic  solution when an acid is dissolved in water we get an  alkaline  solution when an alkali is dissolved in water. 1 miles Acids turn blue litmus to red 2 Acids turn methyl orange to red Bases effect indicators 1 Bases turn red litmus to blue 2 Bases turn methy l orange to yellow 3 Bases turn phenolphthalein to purple Acids neutralize bases producing a salt and water Ba 5734757347573473KRQH HEVLWH5737357347KWWS573735736257362ZZZ57361FROODERUDWLYHOHDUQLQJ57361RUJ 557347680055734725734765734735136573471573472855734771573477976 7KH57347SURMHFW57347LV57347D57347WHDFKHU57347QHWZRUN5735957347DQG57347D57347QRQ57360SUR57536 Dr. .

Acids are named depending on whether they are oxyacids (ternary acids) or non-oxyacids (binary acids). a pure, dry sample of a soluble salt from an insoluble oxide or carbonate, using a Bunsen burner to heat dilute acid and a water bath or electric heater to evaporate the solution..

Solutions have the same properties throughout.. They can be in solid, liquid or gas form. Acids and bases are solutions. . while alkalis produce an excess of hydroxide ions. At neutral pH 7 the two are equal. A 5% solution of baking soda in water exhibits a pH of about 8 measured by a pH meter. A solution with pH 8 is con Amino acids are weak . polyprotic. acids . .
