In chemistry, an alkali is an aqueous (from water) solution with a pH value of more than 7. The word 'Alkali' comes from the Arabic 'qali' meaning 'from the ashes' since ashes mixed with water used as cleaning products (such as soaps) are made of alkali materials.. An alkali is where a base is dissolved in water. Often it is the salt of an Alkali metal An …Web

Saline-alkali stress is a widespread adversity that severely affects plant growth and productivity. Saline-alkaline soils are characterized by high salt content and high pH values, which simultaneously cause combined damage from osmotic stress, ionic toxicity, high pH and HCO3−/CO32− stress. In recent years, many determinants of salt …Web

Figure 12.1 shows the effect of acid and base in water. Generally, acid reacts with metals, metal oxides, metal hydroxides, and metal carbonates, and a salt is produced. Acids also react with alkalis to form salts and water, otherwise called neutralization reactions. The pH scale measures the extent to which a substance is acidic or basic.Web
